Posted by Anon on Thursday, January 17, 2008 at 10:32am.

A vacant, 1560 kg car begins from rest and rolls 46 meters down an inclined plateau before rolling off the edge and crashing into the sea below. The plateau is at a constant downward angle of 12.4 degrees with the horizontal. The coefficient of rolling friction between the car and the plateau is 0.125 and the edge of the plateau is 55 meters above the sea.

At what rate was the car accelerating as it rolled down the plateau?
