Q:
Q7 Q1.) How much work is done pulling the box 20 feet along the ramp?
Accepted Solution
A:
incline of ramp = 10 degrees
rope = 33 degrees
33-10 = 23 degree angle of force
force on the ramp = 80 pounds x cos(23 degrees) = 73.64 pounds of force
work = 73.64 x 20 foot long ramp = 1472.8 = 1473 foot-pounds
