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.

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.

You are given a sample of metal and asked to determine its specific heat. You weight the sample and find that its weight is 28.4n.Ypu carefully add of heat heat energy to he sample and find that its temperature rises.Ehat is the samples specific heat?

Answers

Answer:

The samples specific heat is 14.8 J/kg.K

Explanation:

Given that,

Weight = 28.4 N

Suppose, heat energy [tex]E=1.25\times10^{4}\ J[/tex]

Temperature = 18°C

We need to calculate the samples specific heat

Using formula of specific heat

[tex]Q=mc\Delta T[/tex]

[tex]c=\dfrac{Q}{m\Delta T}[/tex]

Where, m = mass

c = specific heat

[tex]\Delta T[/tex] = temperature

Q = heat

Put the value into the formula

[tex]c=\dfrac{1.25\times10^{4}}{\dfrac{28.4}{9.8}\times(18+273)}[/tex]

[tex]c=14.8\ J/kg. K[/tex]

Hence, The samples specific heat is 14.8 J/kg.K

A car accelerates from 1.5 to 18 m/sec in 9.6 seconds. Calculate its acceleration. and the other one is During a race, you speed up from 2.2 m/sec to 4 m/sec in 3.2 seconds. (a) What is your change in speed? ____ m/sec (b) What is your acceleration? ___ m/sec2

Answers

Answer:

(1) The acceleration is 1.72 m/s²

(2) (a) The change in speed is 1.8 m/s

(2) (b) The acceleration is 0.563 m/s²

Explanation:

(1)

Given;

initial velocity, u = 1.5 m/s

final velocity, v = 18 m/s

time of motion, t = 9.6 s

The acceleration is given by;

a = (v - u) / t

a = (18 - 1.5) / 9.6

a = 1.72 m/s²

(2)

Given;

initial speed, u = 2.2 m/s

final speed, v = 4 m/s

time of motion, t = 3.2 s

(a) The change in speed is given by;

Δv = v - u

Δv = 4 m/s  - 2.2 m/s

Δv = 1.8 m/s

(b) the acceleration is given by;

a = Δv / t

a = 1.8 / 3.2

a = 0.563 m/s²

A jet airliner moving initially at 538 mph (with respect to the ground) to the east moves into a region where the wind is blowing at 937 mph in a direction 23 degrees north of east. What is the new speed of the aircraft with respect to the ground. Answer in units of mph

Answers

Answer:

The speed is "1447.576 mph".

Explanation:

The given values are:

Direction (north to east)

= 23°

Wind's speed

= 937 mph

Jet moving at a speed

= 538 mph

Now,

The velocity of jet airliner with respect to the ground will be:

⇒ [tex]v=v_{1}+v_{2}[/tex]

⇒ [tex]v=\sqrt{(538)^2+(987)^2+2(538)(937)\times Cos23^{\circ}}[/tex]

⇒    [tex]=1447.576 \ mph[/tex]

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.
