A block of mass 1.11 kg is placed on a frictionless floor and initially pushed northward, whereupon it begins sliding with a constant speed of 5.86 m/s. It eventually collides with a second, stationary block, of mass 3.77 kg, head-on, and rebounds back to the south. The collision is 100% elastic. What will be the speeds of the 1.11-kg and 3.77-kg blocks, respectively, after this collision?

A 2.1-kg object moving in the positive x-direction at 5.2 m/s collides with a 1.7-kg object moving in the positive y-direction at 8 m/s. The two masses stick together after the collision. With what speed does this composite object move?
One object is at rest, and another is moving. The two collide in a one-dimensional, completely inelastic collision. In other words, they stick together after the collision and move off with a common velocity. Momentum is conserved. The speed of the object that is moving initially is 22 m/s. The masses of the two objects are 3.1 and 7.1 kg. Determine the final speed of the two-object system after the collision for the case (a) when the large-mass object is the one moving initially and the case (b) when the small-mass object is the one moving initially. (a) Vf = i (b) vf= i

Same situation as before. This time it s a block of mass 1.45 kg sliding with a constant velocity of 4.84 m/s to the north, which collides 100% elastically with a second, stationary block, of mass 4.08 kg, head-on, and rebounds back to the south, eventually colliding 100% elastically with a wall and rebounding northward. It then overtakes the second block, which is still moving north as a result of the first collision. What will be the speeds of the 1.45-kg and 4.08-kg blocks, respectively, after their SECOND collision with one another? 0.92 m/s and 2.65 m/s 2.30 m/s and 7.88 m/s 3.44 m/s and 0.90 m/s 3.12 m/s and 4.39 m/s
