Question

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 0.270. The suitcase travels 3.90 m along the ramp.

Part A Calculate the work done on the suitcase by F⃗ . Express your answer with the appropriate units. WF =J Part B Calculate the work done on the suitcase by the gravitational force. Express your answer with the appropriate units. WG =J Part C Calculate the work done on the suitcase by the normal force. Express your answer with the appropriate units. WN =J Part D Calculate the work done on the suitcase by the friction force. Express your answer with the appropriate units. Wf = Correct Part E Calculate the total work done on the suitcase. Express your answer with the appropriate units. Wnet = Correct Part F If the speed of the suitcase is zero at the bottom of the ramp, what is its speed after it has traveled 3.90 m along the ramp? Express your answer with the appropriate units. v =
