Problem 63P

A luggage handler pulls a 20.0-kg suitcase up a ramp inclined at 25.0° above the horizontal by a force of magnitude 140 N that acts parallel to the ramp. The coefficient of kinetic friction between the ramp and the incline is ???k = 0.300. If the suitcase travels 3.80 m along the ramp, calculate (a) the work done on the suitcase by the force ; (b) the work done on the suitcase by the gravitational force; (c) the work done on the suitcase by the normal force; (d) the work done on the suitcase by the friction force; (e) 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 traveled 3.80 m along the ramp?

Step-by-Step Solution:

Solution 63P Step 1 of 6: a) W = (Fcos) s F 0 Both F and s are parallel to the incline and in the same direction, so = 90 and W F F = s140 N)(3.8) = 532 J Step 2 of 6: b) W w (wcos)s 0 W w (196 Ncos(115 )3.8 m = 315 J Step 3 of 6: 0 c) The normal force is perpendicular to the displacement, so W = 0nsince = 90
