Question:

Motion under gravity?

A crane lifts a skip of concrete of mass 6125kg through a vertical distance of 106mDetermine the minimum power rating the motor would require if the lift can take no longer than 120 seconds(Take gravity to be 10m/s^2)

Answer:

A crane lifts a skip of concrete of mass 6125kg through a vertical distance of 106mDetermine the minimum power rating the motor would require if the lift can take no longer than 120 seconds(Take gravity to be 10m/s^2) Power work ÷ time Work force distance Force weight mass 9.8 Work 6125 9.8 106 Power work ÷ time Power work ÷ 120 Power
