A particle of mass m = 10 kg moves along the x-axis. A graph of its potential energy as a function of x is shown. (a) If the particle is released at rest at x = 3.0 m, what direction will it move (if at all)? (b) If the particle is released at x = 1.0 m with velocity v = -2.0 m/s, what speed will it have at x=0? (c) In the case described in part (b), what are the turning points, if any, of the motion?
