Questions 8-10 refer to a toy car which is given a quick push so that it rolls up an inclined ramp. After it is released, it rolls up, reaches its highest point and rolls back down again. Friction is so small it can be ignored. A car sits on a ramp facing down the ramp to the right. Use one of the following choices (A through G) to indicate the net force acting on the car for each of the cases described below. Answer choice J if you think that none is correct. A. Net constant force down ramp. B. Net increasing force down ramp. C. Net decreasing force down ramp. D. Net force zero. E. Net constant force up ramp. F. Net increasing force up ramp. G. Net decreasing force up ramp. The car is moving up the ramp after it is released.
