A 1000 -lb weight is being lifted to a height 10 feet off the ground. It is lifted using a rope which weighs 4 lb per foot and which is being pulled up by construction workers standing on a roof 30 feet off the ground. Find the work done to lift the weight.
Using the Definite Integral
Applications to Physics
A heavy rope, 20 ft long, weighs 0.8 lb/ft and hangs over the edge of a building 100 ft high. a) How much work is done in pulling the rope to the top of the building? Work = ft-lb. a) How much work is done in pulling half the rope to the top of the building? Work = ft-lb.
