Question
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. Net constant force down ramp Net increasing force down ramp Net decreasing force down ramp Net constant force up ramp Net increasing force up ramp Net decreasing force up ramp Net force zero ! 8. The car is moving up the ramp after it is released. -9. The car is at its highest point. -- -10. The car is moving down the ramp.Explanation / Answer
8. The car is moving up the ramp after it is released.
F) Net increasing force up ramp
Explanation: Since the car is moving up, it has to overcome the component of gravity along the incline.
9. The car is at its highest point.
d) Net force is zero
Explanation: Since car is at its highest point and stationery, so net force acting will be zero
10. The car is moving down the ramp.
J) None is correct
As the car is moving downward, we are not sure whether it is accelerating or not. Therefore we can predict about downward force.
