8.1 Potential Energy The only force acting on a particle is conservative force F. If the particle is at point A, the potential energy of the system associated with the particle is 42.0 J. If the particle moves from point A to point B, the work done on the particle by the system is -21.0 J. What is the potential energy of the system with the particle at B? i Save for Later Submit Answer

Problem #1–The below figure shows a 200-kg sleigh being pulled along a ramp at constant velocity. Suppose that the ramp is at an angle of 0 = 30° with respect to the horizontal and the sleigh covers a distance d = 20 m up the incline. The snowy slope is extremely slippery generating a frictionless surface. How much work is done by each force acting on the sleigh?
