What is the speed of a 180 g ball if its kinetic energy is 100 J?

Answers

Answer 1

Answer:

Velocity, V = 33.33 m/s

Explanation:

Given the following data;

Mass = 180grams to kilograms = 180/1000 = 0.18 kg

Kinetic energy = 100J

To find the speed;

Kinetic energy can be defined as an energy possessed by an object or body due to its motion.

Mathematically, kinetic energy is given by the formula;

[tex] K.E = \frac{1}{2}MV^{2}[/tex]

Where;

K.E represents kinetic energy measured in Joules.

M represents mass measured in kilograms.

V represents velocity measured in metres per seconds square.

Substituting into the equation, we have;

100 = ½*0.18*V²

Cross-multiplying, we have;

200 = 0.18*V²

V² = 200/0.18

V² = 1111.11

Taking the square root of both sides, we have;

Velocity, V = 33.33 m/s

Newton's second law states that the acceleration of an object is directly related to the force on it, and inversely related to the mass of the object. You need more force to move or stop an object with a lot of mass (or inertia) than you need for an object with less mass. .

What is the velocity of a 24 kg object with 108 kg m/s of momentum?

A) 3 m/s
B) 4.5 m/s
C) 6 m/s
D) 84 m/s

Answers

Answer:

The velocity of the object is 4.5 m/s

Explanation:

Momentum is equal to mass times velocity.  We can rearrange that relationship to say that velocity is equal to momentum divided by mass.  With that we can say:

v = 108 kg m/s / 24kg

v = (108 / 24) m/s

v = 4.5 m/s

a force of 25N acts on an object. The work done by the force is 400J. How far dose the object move in the direction of the force?

A. 6.3cm
B. 16cm
C. 16m
D. 10km​

Answers

Answer:
C
Explanation:
d=w/f
d=400/25
d= 16

The distance moved by the object in the direction of the force is equal to 16 m. Therefore, option (B) is correct.

What is the work?

Work can be demonstrated as the energy employed when a force is exerted to move an object through a specific distance. The work done depends upon both the exerted force on the object and the displacement.

The action of the force when the object is moving in a straight line in the direction of the exerted force over a distance 'd'.

W= F ×d

Where 'd' is the displacement, 'F' is the applied force and W is the work done.

Given, the work done by the applied force, W = 400 J

The force applied on the object, F = 25 N

The distance moved by the object, d = W/F

d = 400/25

d = 16 m

Therefore, the object moves a distance of 16 m in the direction of the force.

If a ball that is 10 meters above the ground is thrown horizontally at 5.51 meters per second. a. how long will it take for the ball to hit the ground? b. how far will the ball travel in the horizontal direction before it hits the ground?​

Answers

Answer:

a. t = 1.43 s

b. d = 7.88 m

Explanation:

a. The time of flight can be found using the following equation:

[tex] y_{f} = y_{0} + v_{0_{y}}t - \frac{1}{2}gt^{2} [/tex]

Where:

[tex]y_{f}[/tex]: is the final height = -10 m

[tex]y_{0}[/tex]: is the initial height = 0

[tex]v_{0_{y}}[/tex]: is the initial speed in the vertical direction = 0

g: is the acceleration due to gravity = 9.81 m/s²

By solving the above equation for "t" we have:

[tex] t = \sqrt{\frac{2y_{f}}{g}} = \sqrt{\frac{2*10 m}{9.81 m/s^{2}}} = 1.43 s [/tex]

Hence, the ball will hit the ground in 1.43 s.

b. The distance in the horizontal direction can be found as follows:

[tex] x_{f} = x_{0} + v_{0}t + \frac{1}{2}at^{2} [/tex]

Where:

x₀: is the initial position in the horizontal direction = 0

a: is the acceleration in the horizontal direction = 0 (it is moving at constant speed)

[tex] x_{f} = 5.51 m/s*1.43 s = 7.88 m [/tex]

Therefore, the ball will travel 7.88 m before it hits the ground.

Native American children chasing chickens, the sweet smell of wheat on the air, and- a giant dam? The Grand Coulee dam left an enormous impact. Whether it was a negative or a positive impact, we're going to find out. While dams are a great way to decrease the use of fossil fuels, construction leaves a massive negative impact. For example, the Grand Coulee Dam made salmon unable to migrate downriver to lay their eggs, thus forcing salmon to overpopulate or die out in that area. Another negative impact on the environment was getting materials to build the dam. I mean, those 12 million cubic yards of concrete had to come from somewhere. Another notable impact was the death count. Seventy-seven workers died while building the Grand Coulee Dam, and it took eight years to construct it. Even though the 1930s were called the Great Depression, I'm sure these people still had a lot to live for, and these families must have been sorry to see them go. While there were many negative impacts, the dam still helped society in many ways. For example, it still provides more than twenty-one billion kilowatts of electricity each year, and the energy is clean. Meaning, it doesn't pollute the air or the water. The environment was also affected healthily. All that extra water helps trees and undergrowth, along with fish and land animals. Crops were also healthier and the economy grew. The dam also provided the power needed to make aluminum, which helped during World War II.
