1. The problem statement, all variables and given/known data An elevator cab has a mass of 4600 kg and can carry a maximum load of 1800 kg. If the cab is moving upward at full load at 4.50 m/s, what power is required of the force moving the cab to maintain that speed? 2. Relevant equations P = W/T W = F*D F = M*A 3. The attempt at a solution P = W/T P = (F*D)/T P = ((M*A)*D)/T P = ((6400*9.8)*D)/T I don't know what I should enter for D and T Help, please?
