One object is at rest, and another is moving. The two collide in a one-dimensional, completely inelastic collision.

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 the 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 3.9 and 9.0 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=
(b) vf = i
Vf=
M.
