You are designing equipment and procedures to assist astronauts in building a settlement on Mars. Recall that the gravity on Mars is 3.71 meters per second squared . The astronauts must lift shipping containers onto a platform 5.75 meters (m above the ground. Each container weighed 650 pound-force [lbf] when measured on Earth before transporting the container to Mars. Suppose the motor on the crane is rated at 150 watts [W] and is 60% efficient. How long will it take to lift the container to the platform in units of seconds [s?
