A 5.00-kg package slides 1.50 m down a long ramp that is inclined at 24.0º below the horizontal. The coefficient of kinetic friction between the package and the ramp is 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?
