Does crane A and B have anything in common?
They are both using rope and pulley systems to lift a load from a truck to the top of a building
something is missing.
that's all that was given in the problem
P(A) = W(A)/t = 9492/12.492•60 = 12.66 W
P(B) = P(A)/2 = 6.33 W
W(B) = P(B) •t = 6.33•12.492•60 = 4946 W
