A 5-kg package is pushed 2 m up a ramp that is inclined at 12° above the horizontal by a 100-N force that is parallel to the ramp. The coefficient of friction between the package and the ramp is 0.30. (a) What is the work done on the package by the applied force? (b) What is the work done on the package by friction? (c) What is the work done on the package by gravity? (d) What is the work done on the package by the normal force? (e) What is the total or net work done on the package? (f) If the package started from rest, what is the speed after sliding 2m up the ramp? Use Work-energy equation. (g) If the package is pulled with an initial speed of 2 m/s, what is the speed after sliding 2m up the ramp? Use Work-energy equation.
