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 29 m/s. The masses of the two objects are 2.8 and 8.8 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.

5. A block of mass 1.93 kg is placed on a frictionless floor and initially pushed northward, whereupon it begins sliding with a constant speed of 4.51 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.
