A 1,684-kg car starts from rest at the top of a driveway 6.3 m long that is sloped at an angle of 31 degrees with the horizontal. If an average friction force of 2,622 N impedes the motion of the car, find the speed (in m/s) of the car at the bottom of the driveway. Use the approximation that g 10 m/s2. Answer: m/s (round to the nearest hundredth)
