A 4.50 kg package slides 1.30 m down a long ramp that is inclined at 10.8° below the horizontal. The coefficient of kinetic friction between the package and the ramp is ?k= 0.310.

(a) Calculate the work done on the package by friction.

(b) Calculate the work done on the package by gravity.

(d) Calculate the total work done on the package.

(e) If the package has a speed of 2.4 m/s at the top of the ramp, what is its speed after sliding 1.30 m down the ramp?
