1. The problem statement, all variables and given/known data An elevator has a mass of 956 kg and car- ries a maximum load of 764 kg. A constant frictional force of 4150 N retards its motion upward. The acceleration of gravity is 9.8 m/s2 . What power must the motor deliver at a instantaneous speed of 4.69m/s if the elevator is designed to provide an upward acceleration of 1.07 m/s2? Answer in units of W. 3. The attempt at a solution F=ma N-mg=(me+ml)a N=(me+ml)(a+g) F=N-frictional force P=Fv I was wondering if this progression of the problem would be logical to solve for the power.
