A 2.80*10^2 kg piano is being lifted at a steady speed from ground level straight up to an apartment 12.0 m above the ground. The crane that is doing the lifting produces a steady power of 4.00*10^2 W. How much time does it take to lift the piano? i know that i have to use the equation Time= Work/Power. Power is given. How would I find work? i know that work=F*distance. Would work= 280*9.8*12.0=32928?
