A pool ball initially moves at a constant speed of 4.00 m/s on a horizontal pool table. Another pool ball is initially at rest. The twoballs collide. Friction and air resistance can be ignored, and the collision is perfectly elastic. The masses of the two pool balls are0.2 kg each. Select all of the following final speeds that are possible for the two pool balls.Check All That Apply2.00 m/s, 2.00 m/s200 m/s. 346 m/s

In an elastic collision, both momentum and energy are conserved. It means momentum and energy will…

A 10-m-long glider with a mass of 680 kg (including the passengers) is gliding horizontally through the air at 20 m/s when a 60 kg skydiver drops out by releasing his grip on the glider. What is the glider's speed just after the skydiver lets go?
A 719-N man stands in the middle of a frozen pond of radius 4.0 m. He is unable to get to the other side because of a lack of friction between his shoes and the ice. To overcome this difficulty, he throws his 1.2-kg physics textbook horizontally toward the north shore at a speed of 4.0 m/s. How long does it take him to reach the south shore?
One block of mass m_1=2.0 kg is sliding down along a frictionless ramp from a height of h=2.5 m. It then collides with another block of mass m_2=1 kg and after the collision the stick together. Then, both of the blocks slide together into a region where the coefficient of kinetic friction is 0.500 and comes to a stop after distance d m within that region. a. Find the velocity of the block of mass m1 at the bottom of the ramp. b. Find the velocity of the two-block at which they slide into the region with kinetic friction coefficient 0.500. c. Find the value of distance d at which they stop
James realizes that he can try to get Kevin by having two balls roll down from opposite hills. Ball one is 15kg and is being rolled down a hill of height 32m, ball two is 20kg, and is rolling down in the opposite direction from a height of 18.5m. What are their final velocities at the bottom of the hill? If they are now on a flat plane and collide in a completely elastic collision, what are their final speeds after the collision?

. In an experiment, you throw a rubber ball of mass m = 25.0 g onto a block of mass M = 250 g that is initially at rest at the edge of a table of height h = 0.98 m. (Figure) The ball bounces back with a speed of 1.01 m/s, and the block eventually lands at d = 1.02 m from the bottom of the table. What is the speed of the ball, right before it hits the block?
A small (35 g) block is sliding toward the right along a table when it hits a larger (90 grams) block that was at rest. After the collision, the large block slides 72 cm to the right before coming to a rest, while the small block bounces off the large block, sliding 1.5 m to the left before stopping. The somewhat rough table has a coefficient of kinetic friction of 0.42. What is the velocity of the small block just before it hits the larger block?
A block of mass m1 = 15.5 kg slides along a horizontal surface (with friction, μk = 0.29) a distance d = 2.65 m before striking a second block of mass m2 = 5.25 kg. The first block has an initial velocity of v = 9.25 m/s. What is the speed of m1, in m/s, right before it collides with m2? Assuming that block one stops after it collides with block two, what is block two's velocity after impact in m/s?
Two blocks with masses m1 = 1.4kg and m2 = 4.6kg are at rest on a frictionless surface with a compressed spring between them. When the blocks are let go, block 1 is observed to have a velocity of 4.4m/s to the left. What is the speed of block 2?

Male bighorn sheep (120 kg ) engage in head-butting contests to establish dominance. High-speed photography has shown that the impact speed is typically 6.0 m/s and that the collision, which brings both rams to a halt, lasts approximately 0.25 s . Suppose the collision force increases linearly with time until it reaches a maximum Fmax , then decreases linearly to zero at t = 0.25 s. What is Fmax?
A rocket-powered sled sits on a frozen lake bed. The sled has a mass of 210 kg, and the combusting rocket fuel has a mass of 8 kg. In a simplified analysis, we assume that as a result of combustion, the rocket fuel is fired backward at a speed of 160 m/s. What final speed does the sled achieve?
A baseball has a mass of 0.140 kg, and it is pitched towards home plate at a speed of 48.0 m/s. Assume that the ball is pitched horizontally and that the ball is hit horizontally back in the opposite direction. If the bat exerts an average force of 9100 N for 2.80 ms, what is the final speed of the ball in m/s?
