1. The problem statement, all variables and given/known data The motor of an elevator can produce 14kW of power, its mass is 1100kg. At what constant speed will the elevator rise? 2. Relevant equations F=ma W= Fd P= w/t Vav= d/t 3. The attempt at a solution P= w/t P= Fd/t P= F * Vav V= P/mg = 14000W/(1100Kg*9.8m/s^2)=1.29m/s The book states the answer is 13m/s. I have no idea how I'm suppose to get this answer, please help. Thanks in advance.
