In a game of pool, the cue ball strikes another ball of the same mass and initially at rest. After the collision, the cue ball moves at 3.50 m/s along a line making an angle of 22.0 with the cue ball’s original direction of motion, and the second ball has a speed of 2.00 m/s. Find (a) the angle between the direction of motion of the second ball and the original direction of motion of the cue ball and (b) the original speed of the cue ball. (c) Is kinetic energy (of the centers of mass, don’t consider the rotation) conserved?
The last stage of a rocket, which is traveling at a speed of 8300 m/s, consists of two parts that are clamped together: a rocket case with a mass of 370 kg and a payload capsule with a mass of 140 kg. When the clamp is released, a compressed spring causes the two parts to separate (with the payload being propelled forward and the rocket case backward) with a relative speed of 720 m/s. What are the speeds of (a) the rocket case and (b) the payload after they have separated? Assume that all velocities are along the same line. Find the total kinetic energy of the two parts (c) before they seperate?

Two blocks slide on a collision course across a frictionless surface, as in the figure. The resulting collision is inelastic. The first block has mass M = 1.40 kg and is initially sliding due north at a speed of V, = 8.75 m/s. The second block has mass m = 7.00 x 10-2 kg and is initially sliding at a speed of v, = 11.5 m/s directed at an angle 0 = 27.5° south of east. Immediately after the inelastic collision, the second block is observed sliding at v, = 5.15 m/s in a direction of o = 17.5° north of east. V, Block 2 V, Block 1 Determine the components of the first block's velocity after the collision. Vyf = X m/s Vyf = X m/s
A lumberjack is standing on a log floating on a lake. She starts from rest, then runs along the log to the end, when she jumps from the first log onto a second. After landing safely on the second log, she slows down and ends up standing on the second log. Both logs both have masses of 150 kg each and the mass of the lumberjack is 70 kg. The lumberjack reaches a speed of 7.0 m/s relative to the shore during her jump. What is the speed of the lumberjack after she has stopped on the second log? You may assume the drag of the water on the logs is very small. Please answer in units of m/s.
