Problem 6.9: A 12-kg box slides down a rough ramp
Please wait for the animation to completely load.
A 12-kg box slides down a rough 26.56° ramp at constant speed (it is already traveling at this constant speed at t = 0 s and continues to do so even after the animation ends) as shown in the animation (position is given in meters and time is given in seconds). Note that both gravity and friction do work on the box. Restart.
- What is the work done by friction (done on the box and the ramp) during the animation?
- What is the work done on the box by gravity during the animation?
- What is the total work done on the box during the animation?
