A crane lifts a 2.75x10^3N bucket containing 1.20 m^3 of soil (density = 2.00 x10^3 kg/m3)to a height of 6.95m?
Calculate the work the crane performs.
Answer:
Crane work = weight to be lifted x 6.95 m Weight to be lifted = 2.75x10^3 N + 1.20 m^3 (2.00 x 10^3 kg/m^3) (9.8) = 2750 + 23520 = 26270 Therefore, Crane work = 26270 x 6.95 = 182576.5 J
