A particle, constrained to move along the x-axis, has a total mechanical energy of -100 J. The potential energy of the particle is shown in the graph. At time t = 0, the particle is located at x = 5.5 cm and is moving to the left. (a) What is the particle’s potential energy at t = 0? What is its kinetic energy at this time? (b) What are the particle’s total, potential, and kinetic energies when it is at x = 1 cm and moving to the right? (c) What is the particle’s kinetic energy when it is at x= 3 cm and moving to the left? (d) Describe the motion of this particle starting at t = 0.
