SUMMARY
An electric motor generates 65 kW of power while lifting a loaded elevator 17.5 meters in 35 seconds. To determine the force exerted by the motor, one must utilize the relationship between power, force, and velocity. The relevant equation is Power = Force x Velocity, where velocity can be calculated as distance divided by time. By substituting known values, the force can be derived without needing the mass directly.
