Problem 5.7

Please wait for the animation to completely load.

A 12-kg box slides on a rough (meaning that there is friction) 26.56° ramp as shown in the animation  (position is given in meters and time is given in seconds).  Restart.

1. Draw a free-body diagram for the box, showing all the forces that act.
2. What is the net force on the box?  Include both magnitude and direction in your answer.
3. What is the value for the coefficient of kinetic friction?
