Question

On the way to work, a person in a 6613.48 lb vehicle, with front-wheel drive, coasts down a 5.00 degree hill at constant velocity. (Neglect air resistance).

A) Determine the static friction force, Ffrs, between the tires and the road.

-On the way home, the same vehicle moves up the same hill, at constant velocity.

B) Determine the static friction force applied by the front-wheel tires as it moves up hill at constant velocity to show that the static friction force is approximately 5.13kN.

(Hint: you will need to use the static friction force from part A in this part of the problem)

C) Determine the maximum acceleration of the vehicle if it were traveling on a level road and the front-wheels were applying he same force from part B.
