A luggage handler pulls a 19.0-kg suitcase up a ramp inclined at 34.0 ∘ above the horizontal by a force F⃗ of magnitude 169 N that acts parallel to the ramp. The coefficient of kinetic friction between the ramp and the incline is 0.330. The suitcase travels 3.90 m along the ramp.
a)Calculate the work done on the suitcase by F⃗ .
Express your answer with the appropriate units.
b)Calculate the work done on the suitcase by the gravitational force.
c)Calculate the work done on the suitcase by the normal force.
d)Calculate the work done on the suitcase by the friction force.
e)Calculate the total work done on the suitcase.
f)If the speed of the suitcase is zero at the bottom of the ramp, what is its speed after it has traveled3.90 m along the ramp?
