A 500-kw motor is used to pull a 200-kg crate up a, Ask an Expert

Academics

A 5.00-kW motor is used to pull a 20.0-kg crate up a 15.0°-incline of length 4.00 m. The coefficient of friction is 0.300. Assume air resistance is negligible for the crate, and assume the motor is 20.0% efficient.

a. At what average velocity can the motor move the crate up the incline?

b. How long will be required for the crate to move up the incline?
