Problem an elevator has mass 600 kg not including, Ask an Expert

Academics

Problem: An elevator has mass 600 kg, not including passengers. The elevator is designed to ascend, at constant speed, a vertical distance of 20.0 m (five floors) in 16.0 s, and it is driven by a motor that can provide up to 40 hp to the elevator.

Part A: What is the maximum number of passengers that can ride in the elevator? Assume that an average passenger has mass 65.0 kg.

I need help to find the maximum number of passengers that can ride in the elevator.
