Block A is placed on a smooth tabletop as shown above, and block B hangs over the edge of the table. The tabletop is a distance 2 h 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 .
a. Determine the acceleration of block B as it descends.
b. Block B strikes the floor and does not bounce. Determine the time t=t1 at which block B strikes the floor.
c. Describe the motion of block A from time t=0 to the time when block B strikes the floor.
d. Describe the motion of block A from the time block B strikes the floor to the time block A leaves the table.
e. Determine the distance between the landing points of the two blocks.
