Two solid iron spheres of masses m and 2m respectively, are suspended from two inextensible ropes of length l. We separate the ball of mass m from its equilibrium position at an angle α, keeping the string extended in the same plane. The mass is released and collides elastically with the sphere of mass 2m. The speed of the sphere sphere of mass m immediately after the collision is:
(Please include diagram or drawing) Two clay meteors, each with a mass m, collide in outer space and stick together. This collision occurs at a distance D from the center of the Earth. Following the collision, the combined meteors move towards the Earth. Before the collision: Meteor 1 has a velocity v1. Meteor 2 has a velocity v2. The velocities V1 and v2 are at right angles to each other. a) Calculate the fraction of kinetic energy lost during the collision of the two meteors. b) Determine the velocity of the stuck-together meteors just before they crash into the Earth assuming you know the mass and radius of earth. Air resistance can be neglected.

The mass of a regulation tennis ball is 57.0 g (although it can vary slightly), and tests have shown that the ball is in contact with the tennis racket for 30 ms. (This number can also vary, depending on the racket and swing.) We assume a 59.0 g ball and a 26.0 ms contact time in this problem. In the 2011 Davis Cup competition, Ivo Karlovic made one of the fastest recorded serves in history, which was clocked at 156 mi//h (70 m/s). Part A: What impulse did Karlovic exert on the tennis ball in his record serve? Take the +x direction to be along the final direction of motion of the ball. Part B: What average force did Karlovic exert on the tennis ball in his record serve? Part C: If his opponent returned this serve with a speed of 55.0 m/s, what impulse did his opponent exert on the ball, assuming purely horizontal motion?

A very elastic rubber ball is dropped from a certain height and hits the floor with a downward speed v. Since it is so elastic, the ball bounces back with the same speed v going upward. Which of the following statement about the bounce are correct? There could be more than one correct choice. A.) The ball had the same momentum just before and just after the bounce. B.) The magnitude of the ball's momentum was the same just before and just after the bounce. C.) The ball's momentum was conserved during the bounce. D.) None of the above statements are correct.

Block m, of mass 15 kg moving with velocity v = 33 m/s on a frictionless plane collides block mg which is connected to block m3 by a long. massless spring with spring constant k = 7000 N/m: see the figure.

B and Cassume that the collision of blocks m, and ma is completely inelastic.
