Question
During that lift, what is the work done on the canister by the weight mg of the canister? (Hint: When a cord loops around a pulley as shown, it pulls on the pulley with a net force that is twice the tension in the cord.)
Will rate ASAP.
In the figure, a cord runs around two massless, frictionless pulleys; a canister with mass m = 35 kg hangs from one pulley; and you exert a force F on the free end of the cord. You must pull the free end of the cord 12 cm to lift the canister by 6 cm. During that lift, what is the work done on the canister by the weight mg of the canister? (Hint: When a cord loops around a pulley as shown, it pulls on the pulley with a net force that is twice the tension in the cord.) Will rate ASAP.Explanation / Answer
There is no acceleration, so the lifting force is equal to the weight of the object. We note that the person
