A 3.0 × 103 kg car accelerates from rest at the top of a driveway that is sloped at an angle of 15.9◦ with the horizontal. An average frictional force of 4.1×103 N impedes the car’s motion so that the car’s speed at the bottom of the driveway is 4.3 m/s.
The acceleration of gravity is 9.81 m/s2 . What is the length of the driveway? Answer in units of m.
