Atwostage rocket moves in space at a constant velocity of +4430 mfs. The two stages are then separated by a small explosive charge placed between them. Immediately after the explosion the velocity of the 103Ukg u pper stage is +5590 mp's. What is the velocity [magnitude and direction} of the 24SUkg lower stage immediately after the explosion? One object is at rest, and another is moving. The two collide in a onedimensional, 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 mis. The masses of the two objects are 2.8 and 9.0 kg. Determine the nal speed of the two-object system after the collision for the case {a} when the largemass object is the one moving initially and the case (b) when the smallmass object is the one moving initially
