A billiard ball rolling across a table at 1.75 m/s makes a head-on elastic collision with an identical ball.
(a) Find the speed of each ball after the collision when the second ball is initially at rest.
m/s (1st ball)
m/s (2nd ball)
(b) Find the speed of each ball after the collision when the second ball is moving toward the first at a speed of 1.10 m/s.
m/s (1st ball)
m/s (2nd ball)
(c) Find the speed of each ball after the collision when the second ball is moving away from the first at a speed of 0.90 m/s.
m/s (1st ball)
m/s (2nd ball)
