A skier (down a straight course) is able to enter the starting gate with a speed of 1 m/sec and the average acceleration down the hill was 3 m/s2. If
the skier covers the course in 10 sec, how fast was he moving at the bottom of the course?
O31 m
O 13 m/s
O-29 m/s
O 31 m/s

Answers

He was moving at 31 m/s

If a skier (down a straight course) is able to enter the starting gate with a speed of 1 m/sec and the average acceleration down the hill was 3 m/s², then he was moving at  31 m / s at the bottom of the course.

What are the three equations of motion?

There are three equations of motion given by  Newton

v = u + at

S = ut + 1/2 × a × t²

v² - u² = 2 × a × s

As given in the problem, a skier (down a straight course) is able to enter the starting gate with a speed of 1 m/sec and the average acceleration down the hill was 3 m/s² .

By using the first equation of the motion,

v = u + at

v = 1 + 3 × 10

v = 31 m / s

Thus, he was moving at  31 m / s at the bottom of the course.

Answers

Answer:

B. is the correct answer just took the topic review.

Explanation:

Edge2020. Hope that this helps! Peace and Love

Courts often depend upon recovered memories is the wrong statement about the hypnotic regression.

What is hypnotic regression?

Hypnotic regression is a contentious method because it can have a number of negative effects on the subjects who undergo it. For the beginners, the memories recovered through any regression can be doubtful and not trust-worthy. All the suggestions or leading questions from the hypnotist or other people of witnesses can affect the memory.

The previous lives memories will be found by the hypnotic technique as a past life regression.  If they used to remember the past life by this method they have high chance of getting into the traumas.

Regression therapy mostly used to identify the cause of your current thoughts and reactions. Therapists who is using this techniques to access subconscious memories that are guiding your current behaviour.

Regression therapy is a method of  treatment that could approach and focuses on resolving particular past events that are thought to be interfering or relatable with a person's current mental and emotional well-being.

Hence, Option B is the correct answer.

Moral Dilemma A man is sitting at home worrying about the fact that his daughter needs a major surgery in order to continue living, but he does not have the money to pay for it. He has asked family and friends to help with the cost of the surgery, but he was only able to raise about a quarter of what the surgery costs. He then remembers that he has power of attorney (i.E., control over someone else's finances/legal issues) for his out-of-touch-with-reality, but healthy, 85-year-old father. The man could, without anyone knowing, use his father's money to pay for the surgery. However, this would leave his father with only one year of living expenses. The man decides to take his father's money for his daughter's surgery. Should the man have done that? Why?

Answers

Answer:

Mostly with aid of Kohlberg 's moral growth theory, I clarify this answer, which would also be separated into three stages under which this particular problem is illustrated below.

Explanation:

Pre conventional Stage:

The daughter's father would think about either the penalty during that point if he commits any wrongdoing or breaches laws to save her daughter. But another way to make that happen for surgery is that a person cares about either the legislation and rules as well as the significance of respecting them throughout the pre-conventional process. He will also attempt to establish its insight into solving these problems.

Conventional Stage:

As per the traditional process of the spiritual psychosocial development of Kohlberg, her father would think of civilization because there are conventions that unless he borrows money of his dad again for the procedure of their daughter, culture would label him greedy or prejudice against him to pay the profits of his father despite his consideration.

Post conventional Stage:

As per this argument, he might determine for her child as well as father in his philosophy including perspectives, which means that his father is not in the situation of requesting credit, but because he's in a position to give a recommendation, therefore he certainly gives authorization rescue her grandchildren even though she is small and has several activities to do in hers life. And subsequently, with emerging profits, he will take care of his father as well as daughter, and nowadays focus says their daughter wants treatment to recover.

A car accelerates uniformly from rest to a speed of 6.6 m/s in 6.5 s. Find the acceleration the car presents during this time?

Answers

Answer:

1.02 m/s²

Explanation:

The following data were obtained from the question:

Initial velocity (u) = 0 m/s

Final velocity (v) = 6.6 m/s

Time (t) = 6.5 s

Acceleration (a) =.?

Acceleration can simply be defined as the change of velocity with time. Mathematically, it can be expressed as:

a = (v – u) / t

Where:

a is the acceleration.

v is the final velocity.

u is the initial velocity.

t is the time.

With the above formula, we can obtain the acceleration of the car as follow:

Initial velocity (u) = 0 m/s

Final velocity (v) = 6.6 m/s

Time (t) = 6.5 s

Acceleration (a) =.?

a = (v – u) / t

a = (6.6 – 0) / 6.5

a = 6.6 / 6.5

a = 1.02 m/s²

Therefore, the acceleration of the car is 1.02 m/s²

A gold puck has a mass of 12 kg and a velocity of 5i – 4j m/s prior to a collision with a stationary blue puck whose mass is 18 kg. After an elastic collision, the blue puck has a velocity of 2i – 2j m/s. What is the velocity of the gold puck after the collision?

A. 2i –j m/s
B. 3i –j m/s
C. 2i – 2j m/s
D. 3i – 2j m/s

Answers

Pick the third one C

The velocity of the gold puck after the collision be (2i - j) m/s.

What is velocity?

The rate at which a body's displacement changes in relation to time is known as its velocity. Velocity is a vector quantity with both magnitude and direction. SI unit of velocity is meter/second.

Given parameters:

Mass of the gold puck: m = 12 kg

Velocity of it before collision: u =  5i – 4j m/s.

Mass of the stationary blue puck: M = 18 kg.

Velocity of it after collision; V = 2i – 2j m/s.

We have to find:  the velocity of the gold puck after the collision: v = ?

From conservation of linear momentum, we get:

Total momentum of the system before collision =  Total momentum of the system after collision

⇒ mu + M.0 = mv + MV

⇒ v = u - MV/m

⇒ v  = (5i – 4j) m/s  - (2i – 2j)m/s×18/12.

⇒ v  = (5i – 4j) m/s - (3i - 3j) = (2i - j) m/s.

Hence velocity of the gold puck after the collision be (2i - j) m/s.

A skydiver jumps from an airplane traveling 120. km/hr at a height of 1000. m. If his parachute must open 500. m above the ground, how long does he have for the chute to open?

Answers

Answer:

The parachute to open in 15 sec.

Explanation:

Given that,

Velocity = 120 km/hr

Height = 1000 m

If his parachute must open 500. m above the ground.

We need to calculate the time for parachute to open

Using formula of time

[tex]v=\dfrac{d}{t}[/tex]

[tex]t=\dfrac{d}{v}[/tex]

Where, d = distance

t = time

v = velocity

Put the value into the formula

[tex]t=\dfrac{500}{120\times\dfrac{5}{18}}[/tex]

[tex]t=15\ sec[/tex]

Hence, The parachute will be open in 15 sec.

How do elastic energy, kinetic energy, and gravitational energy differ from each other?

Answers

Answer:

Gravitational pulls things to the ground

Elastic is stretched or compressed or a shape or object

Kinetic is kinda like the force of motion

Hope this helps

In the gravitational energy, things are pulled to the ground by gravity, for elastic energy stretched, squeezed, or as a shape or item, and for kinetic energy it is similar to the force of motion.

What is Kinetic energy?

Kinetic energy is the term used in mechanics to describe the impulse that an object experiences as it moves. It is described as the amount of effort needed to move someone of a certain mass to rest to a given velocity. Except for fluctuations in speed, the body retains its acceleration after receiving it during acceleration.

The body uses the same lot of fuel when slowing down from its current rate to a state of rest. Formally, kinetic energy refers to any element in the Lagrangian of such a system that seems to have a derivative with respect to time.
