The mechanism shown in the figure below is used to lift heavy loads. The 165 kg crate Cis being hoisted with velocity 9.9 m/s and acceleration 7.4 m/s2. The motor has a mechanical efficiency € = 0.85. Answer the following 5 questions based on this problem, using the sign convention shown: a. Find the velocity with which the motor is reeling cable in, i.e., the velocity at point P. m/s. (2 marks) b. Find the acceleration with which the motor is reeling cable in, i.e., the acceleration at point P. m/s? (2 marks) C. Find the tension in the cable. N. Give your answer to 4 significant figures. (3 marks) W. d. Find the power required to hoist the crate (the power output of the motor). Give your answer to 4 significant figures. (3 marks) W. e. Find the power that must be supplied to the motor. Give your answer to 4 significant figures. (2 marks)
