The motor A accelerates uniformly from zero to 3600 rev/min in 8 seconds after it is turned

Question:

The motor A accelerates uniformly from zero to 3600 rev/min in 8 seconds after it is turned on at time t = 0. It drives a fan (not shown) which is attached to drum B. The effective pulley radii are shown in the figure. Determine 

(a) The number of revolutions turned by drum B during the 8-second startup period. 

(b) The angular velocity of drum B at time t = 4 s, 

(c) The number of revolutions turned by drum B during the first 4 seconds of motion. Assume no belt slippage.
