QUESTION 3 [20 MARKS] At a given instant, a wheel is rotating with an angular velocity, w = 3 rad/s and angular acceleration, a = 9 rad/s as shown in Figure 3. Determine the acceleration of block B at this instant. If the magnitude of the angular velocity and angular acceleration are similar but it changes the length of AB to 0.75 m, determine a new acceleration of block B either higher or lower than previous [20 Marks) [CO2, PO2, C4] 45 B 60 0.3 m 0.5 m Figure 3 QUESTION 3 [20 MARKS] At a given instant, a wheel is rotating with an angular velocity, w = 3 rad/s and angular acceleration, a = 9 rad/s as shown in Figure 3.
