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 3.2 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
