16. Two small blocks, each of mass m, are connected by a string of constant length 4h and negligible mass. Block A is placed on a smooth (frictionless) tabletop as shown below, and block B hangs over the edge of the table. The tabletop is a distance 2h above the floor. Block B is then released from rest at a distance h above the floor at time t = 0. Express all algebraic answers in terms of h, m, and g. Am -3h- Bm 2h h a. Determine the acceleration of block B as it descends. (2 marks) b. Block B strikes the floor and does not bounce. Determine the time at which block B strikes the floor. (2 marks) c. Determine the distance between the landing points of the two blocks. (4 marks)
