b) The mechanism shown in Figure 2 is used to lift heavy loads. The 100 kg crate C is being hoisted with velocity v = 3 m/s and acceleration a = 0.2 m/s2. By stepping through the following questions, find the power consumption of the motor, which has a mechanical efficiency € = 0.8, at the instant shown: (i) 0 Draw the free-body diagram of the crate clearly showing all the forces acting on it. [1] (ii) Find the velocity with which the motor is reeling string in, i.e., the velocity at point P. [4] (iii) Find the tension in the string. [4] (iv) Find the power required to hoist the crate and also the power that must be supplied to the motor. Р M с Figure Q2
