The potential energy of a certain oscillator is shown in the figure, as a function of position along the x-axis. UA = 10J, UB = 20J, UC = 30J. The mass Of the oscillator is 0.869k•g. The oscillator has an initial speed of —7.5% at x = 4.5M. 1) Find the speed Of the oscillator at x=1m. 2) Find the magnitude and direction Of the force acting on the oscillator at x = 5.5m.
x=2m=20J,x=4m=10J, x=6m=30J
