Required information A particle is constrained to move along the x-axis. The graph describes the potential energy as a function of position. U(J) 4 6 8 10 12 14 x (cm) -200 -400 -600 The particle has a total mechanical energy of -100 J. At time t= 0, the particle is located at x = 8.00 cm and is moving to the left. What is the particle's total energy when it is at x = 2.00 cm
