Block B moves downward with a constant velocity of 20 mm/s. At t 5 0, block A is moving upward with a constant acceleration, and its velocity is 30 mm/s. Knowing that at t 5 3 s slider block C has moved 57 mm to the right, determine (a) the velocity of slider block C at t 5 0, (b) the accelerations of A and C, (c) the change in position of block A after 5 s.

Answer:
Block B shown in figure , moves downwards with a constant velocity of `20 cm//s`. At t = 0, block A is moving upward with a constant acceleration, and its velocity is `3cm//s`. If at `t = 3s` blocks C has moved 27 cm to the right, determine the velocity of block C at t = 0 and the acceleration of A and C.
