A student, while moving out of his old apartment, is loading a rented moving truck using a ramp which is at a rather steep angle of 28.0° above the horizontal; the ramp is 2.90 m long. At one point in the loading process he drags a loaded suitcase of mass 24.50 kg up the full length of the ramp. The wheels on the old suitcase have long since ceased to function properly, so that the effective coefficient of kinetic friction between the suitcase and the inclined ramp is 0.220. The old suitcase has a strap attached to one corner, and the student does the dragging by pulling on this strap and running up the ramp (he is in a hurry) so that he and the suitcase speed up while going up the ramp. It turns out the the student is able to maintain a tension of 173.0 N during his pull, and the angle between the strap and the incline is 19.0° (the strap direction is 19.0° higher than the incline angle). ✔ - Part A How much work is done on the suitcase by the tension force during the pull up the ramp? 15| ΑΣΦ Submit Part B Request Answer ?
