Chapter 6, Problem 6.68(choose chapter or problem)
A 5.00-kg package slides 1.50 m down a long ramp that is inclined at below the horizontal. The coefficient of kinetic friction between the package and the ramp is \(\mu_{\mathrm{k}}=0.310\). Calculate
(a) the work done on the package by friction;
(b) the work done on the package by gravity;
(c) the work done on the package by the normal force;
(d) the total work done on the package.
(e) If the package has a speed of 2.20 m/s at the top of the ramp, what is its speed after sliding 1.50 m down the ramp?
