One object is at rest, and another is moving. The two collide in a one-dimension

Question

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 collision and move off with a common velocity. Momentum is conserved. The speed of the object that is moving initially is 27 m/s. The masses of the two objects are 3.0 and 8.4 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.

Explanation / Answer

V = M1V1/(M1+M2)

a) V= 19.894 m/sec
b) V= 7.105 m/sec
