   F = 3 ˆ  + 5 ˆ  ( 29 N    r = 2 ˆ  - 3 ˆ  ( 29 m Chapter 8: Potential Energy 1.  Dave Johnson, the bronze medalist at the 1992  Olympic decathlon in Barcelona, leaves the ground at the  high jump with vertical velocity component 6.00 m/s.  How far does his center of mass move up as he makes the  jump? 2. Two objects are connected by a light string  passing over a light frictionless pulley as shown in Figure  P8.13. The object of mass 5.00-kg is released from rest.  Using the principle of conservation of energy, (a)  determine the speed of the 3.00-kg object just as the  5.00-kg object hits the ground. (b) Find the maximum  height to which the 3.00-kg object rises. Figure P8.13 3. A particle of mass  m  = 5.00 kg is released from point  A and slides on the frictionless track shown in Figure  P8.24. Determine (a) the particle's speed at points B and  C   and (b) the net work done by the gravitational force in  moving the particle from A to C
