Question

A 4.60kg package slides 1.59m down a long ramp that is inclined at 12.2 below the horizontal. The coefficient of kinetic friction between the package and the ramp is k = 0.316

a- Calculate the work done on the package by friction

b- Calculate the work done on the package by gravity.

c- Calculate the work done on the package by the normal force.

Express your answer to three significant figures.

d- Calculate the total work done on the package.

e- If the package has a speed of 2.22m/s at the top of the ramp, what is its speed after sliding the distance 1.59m down the ramp?

Explanation / Answer

work done by gravity=4.60*9.8*1.59

work done by normal force=mgcos12.2*1.59

work done by friction=0.316*mgcos12.2*1.59

by adding three we get total work done
