A luggage handler pulls a 15 kg suitcase up a ramp inclined at an angle 30⁰ above the horizontal by a horizontal force F of magnitude 180 N. The coefficient of kinetic friction between the ramp and the suitcase is 0.25. If the suitcase travels 1.9 m along the ramp, calculate (a) The work done on the suitcase by F (b) The work done on the suitcase by gravity (c) The work done on the suitcase by friction (d) The work done on the suitcase by normal force (e) If the package started from rest, what is its speed after it has travelled 1.9 m?
