1. The problem statement, all variables and given/known data A 1200kg elevator driven by an electric motor can safely carry a maximum load of 800kg. What is the power provided by the motor when the elevator ascends with a full load at a speed of 2.3 m/s 2. Relevant equations P=F*v 3. The attempt at a solution So I use directly P=F*v=(melevator+mpeople)*g*v However I got the wrong answer. Does it involve any other formula here ?
