Calculus Work Rope problem helpp pleasezz!?
1.) A mountain climber is about to haul up a 50M length of hanging rope. How much work will it take if the rope weighs .624 N/m?
The Work on the rope is W= integral of 0.624xdx from 0 to 50.
2) A 5 lb bucket is lifted from the ground into the air by pulling in 20ft of rope at aconstant speed. The rope weighs 0.08lb/ft. How much much work was spend lifting the bucket and rope.
Just the work on rope = integral of (.08)(20-x)dx from 0 to 20.
My question is how come the work in question one is not 0.624(50-x), and question to is. When do you use the (L-x)? thank you
