A 2000−kg automobile starts from rest at point A on a 6∘ incline and coasts through a distance of 50 m to point B. The brakes are then applied, causing the automobile to come to a stop at point C, 20 m from B.

The speed of the automobile at point B is m/s. Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part.
