Homework 8.2: The 100kg crate is hoisted by the motor M. The motor's pulley has a radius of 4cm. How long does it take to lift the crate 11.25m off the ground (if it starts on the ground) if the motor's torque is 200N*m? Also, calculate the maximum power required to drive the motor (in kW) if its efficiency is 90%. Use g=10m/s^2 for this problem. Neglect the mass of the pulley and cable. M
