1. The ends oof the bar AB are confined to move along the paths shown. At a given instant, A has a celocity of vA = 4 ft/s and an acceleration of αA = 7ft/s2. Determine the angular velocity and angular acceleration of AB at this instant.

2. Bar AB rotates uniformaly about the fixed pin A with a constant angular ω. Determine the velocity and acceleration of block C, at the instant θ= 60o .
