A 9 kg crate is placed at rest on an incline plane (s = 0.8, k = 0.4), whose angle is 60o. It then slides 4 m down the incline.
a.) Find the work done by each force on the crate after sliding this distance:
work done by normal force
work done by gravity
work done by friction force
b.) Using your results from part a, find the speed of the crate after sliding this distance.
c.) Using the work approach only, could you find the time it takes to slide this distance? Discuss the limitations of using the work/energy method vs. using the forces method to solve problems.
