The figure provided shows a car that has run out of gas while driving down a hill and various free-body diagrams. If the car is at the bottom of the valley which free-body diagram best corresponds to the situation if drag and rolling friction are negligible?

A car parked at the top of a hill does not move down the hill due to what type of friction?

A solid cylinder rolls without slipping down an incline starting from rest. At the same time a box starts from rest at the same altitude and slides down the same incline with negligible friction. Which arrives at the bottom first?

One of your classmates claims that the free body diagram for the skidding car above is incorrect. They think that it should have an arrow to represent the car's inertia, which keeps it moving to the left. Evaluate this claim.

Two objects of identical mass begin from rest at the same height at the top of two different hills - hill A and hill B. The hills are inclined at two different angles (see diagram). The objects are released from rest and slide to the bottom; resistance forces can be considered to be negligible. The object on top of hill ____ will have the greatest speed at the bottom of the incline.

Draw the free body diagram of A car moving in the positive x-direction, when suddenlydecelerating applying a force to slow down the vehicle, to a complete stop
