A 1,959-kg car starts from rest at the top of a driveway 7.26 m long that is sloped at an angle of 21 degrees with the horizontal. If an average friction force of 2,338 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)

Question
A 1,959-kg car starts from rest at the top of a driveway 7.26 m long that is sloped at an
angle of 21 degrees with the horizontal. If an average friction force of 2,338 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)
