It is known that the static frictional force between block B and the plate will be overcome and the block will slide when its acceleration reaches 3 m / s2 (Figure 7b_4). If the plate starts from rest at t = 0 s and accelerates uniformly at a rate of 4 rad / s2 , determine the time t and the angular speed of the plate when the block starts to slip (r = 200 mm).
