Situation: A .71-kg billiard ball moving at 2.5 m/s in the x-direction strikes a stationary ball of the same mass. After the collision, the first ball moves at 2.17 m/s, at an angle of 30.0 with respect to the original line of motion. Assuming an elastic collision (and ignoring friction and rotational motion), answer the following questions to find the struck ball's momentum after the collision.
Calculate the initial momentum of the moving billiard ball in kg*m/s.
Calculate the initial momentum of the ball at rest in kg*m/s.
Calculate the x-component of the first ball's final momentum after the collision in kg*m/s.
Calculate the y-component of the first ball's final momentum after the collision in kg*m/s
Using the conservation of momentum in the x-direction, find the struck ball's x-component of momentum.
Using the conservation of momentum in the y-direction, find the struck ball's y-component of momentum.
Now, using the components of the struck ball's momentum you solved for in the previous questions, find the magnitude of the momentum of the struck ball after the collision.
Using the components of the struck ball's momentum after the collision, find the resulting angle of the struck ball's motion below the horizontal.
