Ball A of mass 5.00 kg moves at a velocity of 4.00 m/s, 0° to collide with a stationary, identical ball, B. After the collision ball A moves in a direction of 30.0°; ball B moves toward 300.0°. (a) Determine the momentum of ball A and of ball B after the collision. (b) Find the velocity of each ball after the collision. (c) Show numerically that the collision is elastic.

A baseball pitch was recorded at 105.1 mph, which is 46.98 meters per second. The mass of the ball is 0.14 kg. Part 1- What is the impulse that is required to give the baseball such momentum? Part 2- What is the impulse that is required by the catcher to be able to stop the ball? Part 3- If the impulse from part 2 was applied to the ball over 0.20 seconds, what is the magnitude of the force acting between the catchers mitt and the ball?

A.16 kg marble moving to the right at 1.2 m/s has  a head-on elastic collision with another ball of equal mass moving to the left a .85 m/s. The first ball moves to the left at .85 m/s after the collision.  Find the velocity of the second ball after the collision.  Include the units, put a space between the numerical answer and the units.  Round to the nearest tenth

8. The head of a golf club with a mass of 0.25 kg is moving with a speed of 55 ms¹ just before striking a stationary 50g golf ball. After the collision, the golf club continues to move (in the same direction) but with a reduced speed of 40 ms 1. Use conservation of momentum to find the speed of the golf ball and determine whether or not the collision was elastic. Find the impulse and force acting on the club during impact if the club and the ball are in contact for 0.01 s
