A 6.0 * 103 kg car accelerates from rest at the top of a driveway that is sloped at an angle of 19.3 ◦ with the horizontal. An average frictional force of 4.4*103 N impedes the car's motion so that the car's speed at the bottom of the driveway is 4.

When analyzing forces, it is allowable to break the motion and forces into horizontal and vertical components.
