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. Knowing that slipping is impending during the braking period and neglecting air resistance and rolling resistance, determine the speed of the automobile at point 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.

A golfer hits a ball with an initial velocity of magnitude v0 at an angle a with the horizontal. The ball must clear the tops of two trees and land as close as possible to the flag. Determine v0 and the distance d when the golfer uses a five-iron with a = 26.5∘. When the golfer uses a five-iron with a = 26.5∘, v0 is calculated to be m/s. When the golfer uses a five-iron with a = 26.5∘, the distance is m. Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part.
