Unformatted text preview: whats the sign of K? The kinetic energy decreases, so K is negative PRS 2 In the same situation as above, what are the signs of the work that each force does on the cart? Work from weight=0, work from tension=negative, work from normal force=0 PRS In same situation as above, what is the sign of the net work on the cart? Negative PRS A ball is allowed to roll down a ramp from rest. What happens to the kinetic energy as it rolls down the ramp and what is the sign of K? Kinetic energy increases, so K is positive PRS In the same situation, what forces are on the ball as it rolls down the ramp? Weight, Normal Force, Friction...
