A lab cart of mass m is pulled by a block of mass m in a lab experiment like the one shown in the diagram to the right. Initially, the cart is a distance 2h from the edge of the table and the block is a distance h above the floor. The system starts from rest and is released. Do not use Newton's Second law to solve any part of this problem. State your answers in terms of m, g, and h. Assume that friction is negligible. (i) Determine the speed of the cart when the block lands on the floor (ii) Determine the speed of the cart when the cart reaches the edge of the table.
