In an inelastic collision involving an isolated system, the final total momentum isa) more than the initial momentum. b) exactly the same as the initial momentum. c) less than the initial momentum.

2(a): determine expressions for its acceleration ax(t), velocity vx(t), and position x(t), given that its initial acceleration, velocity, and position are ai, vi, and xi, respectively. (use any variable or symbol stated above as necessary.)
