An elevator has mass 700 kg, not including passengers. The elevator is designed to ascend, at constant speed, a vertical distance of 32.0  m in   25.0 s, and it is driven by a motor that can provide up to 40 hp to the elevator. ( 1hp=746W ) What is the maximum number of passengers that can ride in the elevator? Assume that an average passenger has mass 65.0 kg. You need to round DOWN when you calculate the number of passengers.
