A ball dropped from a height of 4.10 m makes a perfectly elastic collision with the...
An elastic ball os mass M is dropped from the height h above the floor. At the instant the ball is at the height h/2, it is struck by a bullet of mass 0.2M, flying horizontally at the speed v. The bullet gets stuck inside the falling ball. The ball then bounces off the floor several times. What is the horizontal distance x traveled by the ball between the first and second bounce? The acceleration due to gravity is g....
A billiard ball of mass 0.15 kg is dropped from a four story building, corresponding to a height of 12 m. If mechanical energy is conserved, what are the (1) kinetic energy and (2) the velocity of the ball just before it strikes the ground surface? Assume that the ball remains intact after impact and that the collision is elastic (kinetic energy is conserved). By using the definitions given for the kinetic theory of gases in Chapter 1, what is...
A ball with mass of 0.050 kg is dropped from a height of 2.0 m. It collides with the floor, then sticks to the table. The Collison takes 0.020 s. a) Use the conservation of mechanical energy (Ei = Ef) to calculate the velocity of the ball before collision with the floor
A 900 g rubber ball is dropped from height 17.5 m, and it rebounds to height 5.17 m. Assuming there is no air friction and the average force exerted by the ground is 24.5 N, find the time the ball was in contact with the ground.
Starting with an initial speed of 3.76 m/s at a height of 0.469 m, a 1.52-kg ball swings downward and strikes a 5.52-kg ball that is at rest, as the drawing shows. (a) Using the principle of conservation of mechanical energy, find the speed of the 1.52-kg ball just before impact. (b) Assuming that the collision is elastic, find the velocity (magnitude and direction) of the 1.52-kg ball just after the collision. (c) Assuming that the collision is elastic, find...
Starting with an initial speed of 5.40 m/s at a height of 0.329 m, a 2.07-kg ball swings downward and strikes a 4.27-kg ball that is at rest, as the drawing shows. (a) Using the principle of conservation of mechanical energy, find the speed of the 2.07-kg ball just before impact. (b) Assuming that the collision is elastic, find the velocity (magnitude and direction) of the 2.07-kg ball just after the collision. (c) Assuming that the collision is elastic, find...
A ball is dropped from rest at a height h. Directly below on the ground, a second ball is simultaneously t thrown upwards with a speed of vc. The two balls collide at the moment that the second ball is instantaneously at rest. (They collide when the second ball is at its maximum height.) What is the height of the collision? At what time does the collision occur if both balls' motion stated at t = 0 s?
Starting with an initial speed of 6.68 m/s at a height of 0.305 m, a 1.36-kg ball swings downward and strikes a 5.60-kg ball that is at rest, as the drawing shows. (a) Using the principle of conservation of mechanical energy, find the speed of the 1.36-kg ball just before impact. (b) Assuming that the collision is elastic, find the velocity (magnitude and direction) of the 1.36-kg ball just after the collision. (c) Assuming that the collision is elastic, find...

A 320 g rubber ball is dropped from 2.0 m above the ground, bounces, and returns to a maximum height 1.2 m above the ground. If air resistance does –1.8 J of work on the ball, how much energy goes into heating the ground and the ball when it bounces?
