The figure shows a plot of potential energy U versus position x of a 0.230 kg particle that can travel only along an x axis under the influence of a conservative force. The graph has these values: UA = 9.00 J, UC = 20.0 J and UD = 24.0 J. The particle is released at the point where U forms a "potential hill" of "height" UB = 12.0 J, with kinetic energy 6.00 J. What is the speed of the particle at (a)x = 3.50 m and (b)x = 6.50 m? What is the position of the turning point on (c) the right side and (d) the left side?

The figure shows a thin rod, of length L = 2.30 m and negligible mass, that can pivot about one end to rotate in a vertical circle. A heavy ball of mass m = 15.0 kg is attached to the other end. The rod is pulled aside to angle θ0 = 14.0∘ and released with initial velocity v→0 = 0. As the ball descends to its lowest point, (a) how much work does the gravitational force do on it and (b) what is the change in the gravitational potential energy of the ball-Earth system? (c) If the gravitational potential energy is taken to be zero at the lowest point, what is its value just as the ball is released? (a) Number Units (b) Number Units c) Number Units
