Object A has a mass of m, object B has a mass of m/2, and object C has a mass of 2m. (a) If all three objects have the same momentum, rank them in order of increasing kinetic energy. (b)For the same three masses as before, now assume that the objects have the same kinetic energy, and rank them in order of increasing momentum.

    One object is moving and one object is at rest. The two objects then collide in a dimensional, completely inelastic collision. So the two objects stick together after the collision and move off with a common velocity. Momentum of the two-object system is conserved. The masses of the two objects are 5.00 kg and 8.50 kg, respectively. The speed of the moving object masses 5.00 kg before the collision is 22.5 m/sec. Find the final speed of the two-object system...
