a. The tension in the bottom rope can be calculated by considering the forces acting on the system. Since the top block has a tension of 63.0 N in the top rope, the tension in the bottom rope supporting both blocks is also 63.0 N[1].

b. To find the weight of the top block, we can use the fact that the tension in the top rope is equal to the weight of the top block. Therefore, the weight of the top block is 63.0 N[1].
