The crate weighs 100kg and is hoisted by the motor M. Themotor’s pulley has a radius of 4cm. How long does it take to liftthe crate 11.25m off the ground (if it starts on the ground)if the motor’s torque is 200N*m? Also, calculate the maximum powerrequired to drive the motor (in kW) if its efficiency is 90%. Useg=10m/s^2 for this problem. Neglect the mass of thepulley and cable. Try using efficiency and power? and show work,thank you!!
