Answer to Question #37801 in Molecular Physics | Thermodynamics for Shelby

Question

A 4.2 x 10^3 kg car accelerates from rest at the top of a driveway that is sloped at an angle of 18.4 degrees with the horizontal. An average frictional force of 4.1 x 10^3 N impedes the car's motion so that the car's speed at the bottom of the driveway is 4.9 m/s.
the acceleration of gravity is 9.81 m/s^2 . What is the length of the driveway?
