Calculate the velocity and acceleration of the W load and the corresponding angular velocity \omega and angular acceleration \alpha of the double pulley O.
OA = 3" and OB = 6"
Pulley 1: $r_1 = 3", \omega_1 = 1.5 \text{ rad/sec}, \alpha_1 = 3 \text{ rad/sec}^2$
Pulley 2: $r_2 = 3", \omega_2 = 2.5 \text{ rad/sec}, \alpha_2 = -2 \text{ rad/sec}^2$
