In a game of billiards, a ball with a speed � ! hits a second ball non-centrally. The impact is elastic, the second ball is at rest before the impact, and the first ball is deflected by 30° from its original direction of motion by the impact. What is the speed of the second ball after the impact? (Both balls should have the same mass.)

For the preceding problem, find the final speed of the case of each sled for the case of an elastic collision.
Two identical objects (such as billiard balls) have a one-dimensional collision in which one is initially motionless. After the collision, the moving object is stationary and the other moves with the same speed as the other originally had. Show that both momentum and kinetic energy are conserved.
A tennis ball of mass 57.0 g is held just above a basketball of mass 590 g. With their centers vertically aligned, both balls are released from rest at the same time, falling through a distance of 1.20 m, as shown in Figure P6.45. (a) Find the magnitude of the basketballs velocity the instant before the basketball reaches the ground. (b) Assume that an elastic collision with the ground instantaneously reverses the velocity of the basketball so that it collides with the tennis ball just above it. To what height does the tennis ball rebound? Figure P6.45

Two projectiles of mass m1 and m2 , are fired at the same speed but in opposite directions from two launch sites separated by a distance D. They both reach the same spot in their highest point and strike there. As a result of the impact they stick together and move as a single body afterwards. Find the place they will land.
A billiard ball, labeled 1, moving horizontally strikes another billiard ball, labeled 2, at rest. Before impact, ball 1 was moving at a speed of 3.00 m/s, and after impact it is moving at 0.50 m/s at 50 from the original direction. If the two balls have equal masses of 300 g, what is the velocity of the ball 2 after the impact?

Please answer the question correctly is all I want, dont need to show alot of work just for the final answer to be correct, thanks! Two spheres of mass M1 and M2 are arranged one above the other as shown. They are separated by a negligibly small distance (a fraction of a millimeter). They are released from rest and allowed to fall to the ground, a distance h=5.50 m below as shown. Mass M2 collides elastically with the ground and then elastically with mass M1. And 7.035m is not the correct final answer! Calculate the maximum height in meters to which the center of M1M1 rises above the ground after the collision using the following values:D=0.200 md=0.0500 mM1=0.180 kgM2=1.40 kg
