A piece of putty and a rubber ball have the same mass. If you drop them from the same height, which object will produce a greater impulse and why? B. The rubber ball will produce a greater impulse because it will bounce. The putty does not have the ability to create more impulse due to its shape

A 4.0-kg ball has a momentum of 20.0 kg m/s. What is the ball's speed? As we know, momentum= mass*velocity mass = 4 kg momentum= 20 kg-m/s momentum = mass*velocity (speed) velocity (speed) = momentum/mass velocity(speed)=20/4 = 5 m/s The correct answer is B 5.0 m/s

A small economy car (low mass) and a limousine (high mass) are pushed from rest across a parking lot, equal distances with equal forces. The car that receives the greater impulse is the A. limousine B. small economy car C. neither (same for each) The key word in this question is impulse which

Superman is at rest in space when he throws an asteroid that has more mass than he does. Which moves faster, Superman or the asteroid? A. Superman B. The asteroid C. They both move at the same speed. Remember, Superman is at rest and the asteroid has more mass than Superman. Consider the same

If all people, animals, trains, and trucks all over the world began to walk or run towards the east, then A. Earth would spin a bit slower. B. Earth's spin would not be affected at all. C. Earth would spin a bit faster. It is true, the Earth would actually slow down a little due to the motion

A piece of putty moving with 2 units of momentum strikes and sticks to a heavy bowling ball that is initially at rest. After the putty stick to the ball, both are set in motion with a combined momentum that is A. less than 2 units B. 2 units C. more than 2 units D. There is not enough informat

A 1-N apple falls to the ground. The apple hits the ground with an impact force of A. 1 N B. 2 N C. 3 N D. 4 N E. 9.8 N Remember, the pull of gravity on the object does not change the mass of the object. 1 Newton is the same as 0.101971621 kilograms. Mass and weight are NOT the same and tha

Which of the following has the largest momentum? A. A large truck parked in a parking lot. B. A tightrope walker crossing Niagara Falls. C. The science building at your school D. a pickup truck traveling down the highway. E. A dog running down the street The only answer that makes sense in def

A 5.0 kg chunk of putty moving at 10.0 m/s collides with and sticks to a 7.0-kg bowling ball that is initially at rest. The bowling ball with its putty passenger will then be set in motion with a momentum of So if your two objects stick together, it's an inelastic collision. Meaning they will hav

A 2-kg ball is thrown at 3 m/s. What is the ball's momentum? A. 2 kg m/s B. 3 kg m/s C. 6 kg m/s D. 9 kg m/s E. none of these Momentum is mass times velocity. The mass is 2 kg, the velocity is 3 m/s, so the momentum is (2 kg)(3 m/s) = 6 kg m/s.

While roller-skating, Granny collides with her tiny grandson Ambrose who is at rest. Ignoring any friction effects, Amobrose's speed after the collision will be greater when A. Granny catches him and they both move together. B. He and Granny make a bouncing collision, each going in opposite dire

A table tennis ball moving forward with 5 units of momentum strikes and bounces backward off a heavy bowling ball that is initially at rest and free to move. The bowling ball is set in motion with a momentum of A. less than 5 units B. 5 units C. more than 5 units D. not enough information The

The force that accelerates a rocket into outer space is exerted on the rocket by A. the exhaust gases. B. Earth's gravity C. Atmospheric pressure D. rocket's wings E. none of the above The Third law of motion is applied here. The same amount of force pushing out of the rocket is the same as

Two gliders having the same mass and speed move toward each other on an air track and stick together (an air track produces a more frictionless surface for objects to travel on). After the collision, the velocity of the gliders is A. twice the original velocity B. one half the original velocity

A freight train rolls along a track with considerable momentum. If it were to roll at the same speed but had twice as much mass, its momentum would be A. zero B. unchanged C. quadrupled D. doubled The question states that the mass would be doubled, therefore its momentum would be doubled.
