Question

A billiard ball rollir cross a table at 1.30 m/s makes a head-on elastic collision with an identical ball. Find the speed of each ball after the collision when each of the follow y occurs. (a) The second ball is initially at rest. first ball m/s second ball m/s (b) The second ball is moving toward the first at a speed of 1.15 m/s. first ball m/s second ball m/s (c) The second ball is moving away from the first at a speed of 0.80 m/s. first ball m/s second ball m/s Need Help?
