A(b) = 1.28 m/s^2 ↓ (????????), Length of the rope L = 18 m The system is released from rest when yg = 0 at t = 0 and, after 3 s, ittakes the configuration shown. Block B has a constant downwardacceleration of ag (given below). The total length of the rope is L (givenbelow). The masses of the collar A and the block B are maA = 2 kg andmg = 4 kg. Neglect friction in the system.4 mYAa) Determine ya and yg at the instant shown. (After 3 s!)b) Determine the displacement Aya of A from t = 0 to t = 3 s. (Notethat aa is not constant!) (Hint: Use the constraint equation due tothe rope!)c) Determine va and vg at the instant shown.d) Determine the relative velocity of A with respect to B. (Show the direction!)e) Draw the free-body diagrams of A and B and write the equations of motion, EF = mã, for Aand B at the instant shown. (Do not solve the equations!)f) By solving the equations obtained in part (e), determine the acceleration of A, the tension inthe rope, and the normal force on A due to the vertical rod at the instant shown.g) Determine the work done on A by the tension force during the displacement from t = 0 tot = 3 s. (Hint: Use the work-energy principle!)Note: Take ag and L as
