A very elastic rubber ball is dropped from a certain height and hits the floor with a downward speed v. Since it is so elastic, the ball bounces back with the same speed v going upward. Which of the following statement about the bounce are correct? There could be more than one correct choice. A.) The ball had the same momentum just before and just after the bounce. B.) The magnitude of the ball's momentum was the same just before and just after the bounce. C.) The ball's momentum was conserved during the bounce. D.) None of the above statements are correct.
If the momentum of an object is trippled, its kinetic energy will change by what factor? I think it changes 9 times? not sure.
A ball weighing 1 kg moves at a speed of 4 m / s and collides with a ball weighing 2 kg moving towards it at a speed of 3 m / s. What are the speeds of the balls after hitting? Impact is considered absolutely elastic, direct, central.
A 100-kg particle moves with an initial velocity of (4.0i, - 6.0j) m/s. If its velocity changes to v = (3.0i – 8.0j) m/s by the action of a force, determine The net work done on the particle. What principle would you use to solve this problem? The impulse on the particle. True or False: Impulse is equal to the rate of change of momentum.
A 1500 kg car traveling to the north is slowed down uniformly from initial velocity of 20 m/s by a 6000 N braking force acting opposite the car’s motion. Use the impulse-momentum theorem to answer the following questions What is the car’s velocity after 2.00 s? How far does the car move during 2.00 s? How long does it take the car to come to a complete stop?
云 HI 5 F. %24 -10 Part A Jeanette is playing in a 9-ball pool tournament. She will win if she sinks the 9-ball from the final rack, so she needs to line up her shot precisely. Both the cue ball and the 9-ball have mass m, and the cue ball is hit at an initial speed of v. Jeanette carefully hits the cue ball into the 9-ball off center, so that when the balls collide, they move away from each other at the same angle 0 from the direction in which the cue ball was originally traveling (see figure). Furthermore, after the collision, the cue ball moves away at speed vf, while the 9-ball moves at speed vp. (Figure 1) Find the angle 0 that the 9-ball travels away from the horizontal, as shown in the figure. Express your answer in degrees to three significant figures. > View Available Hint(s) For the purposes of this problem, assume that the collision is perfectly elastic, neglect friction, and ignore the spinning of the balls.

Select the correct answer. A fast car is out of control. Why it safer to drive it into a haystack instead of a concrete wall to stop? the contact time and the force are the impulse is increased reduced the cqntact time is extended and the force n the car is reduced O the velocity is increased
