A bumper car with mass m1 = 110 kg is moving to the right with a velocity of v1 = 4.8 m/s. A second bumper car with mass m2 = 2m, = 220 kg is at rest. The two have an elastic collision and the first bumper car rebounds backwards at a speed that is 1/3 of its original speed (1.6 m/s). Assume the surface is frictionless.

Object A traveling east at 8.47 m/s collides with object B traveling west at 2.43 m/s. Object A has mass 2.82 kg and object B has mass 8.24 kg. The collsion takes place in one dimension, and is totally inelastic. Taking east to be positive, find the velocity of object A (in m/s) after the collision.
Car A and Car B are traveling in the same direction (call it i^), with B behind A, and initial speeds vA=5.6 m/s, and vB = 6 m/s. The cars have identical mass m=103 kg, and they experience an elastic collision. Now, this collision is observed by a third person traveling in a car with constant velocity v=6 m/s, traveling in the same direction as the two cars. From the point of view of this person calculate the following: 1)The initial momentum of car A. 2)The initial momentum of car B. 3)The final momentum of car A (you might want to first calculate the final velocity of car A relative to the ground). 4)The final momentum of car B (you might want to first calculate the final velocity of car B relative to the ground). 5)The total final kinetic energy: 6)The total final kinetic energy as measured from the ground. 7)Based on the previous answers and your calculations of the total initial kinetic energy, does the third person conclude that the collision is:

Two metal blocks are sliding across a frictionless floor. Block one has a mass of 4.75 kg and is sliding with a velocity of 3.25 m/s east (take east to be the positive x-direction). Block two has a mass of 7.25 kg and is sliding with a velocity of 7.39 m/s north (take north to be the positive y-direction). They collide and bounce apart but it is NOT a perfectly elastic collision. After the collision, block one is moving at 4.50 m/s at 75.0º north of east.
