Q1. Consider a one dimensional elastic collision between a moving object A and an object B initially at rest. How would you select the mass of B, in comparison to the mass of A, in order that B should recoil with the greatest speed?
Q2. A 47 kg block is suspended from a uniform chain that is hanging from the ceiling. The mass of the chain itself is 16kg, and the length of the chain is 1.5m. What is Tension in the chain at the point where the chain is attached to the block? What is the tension of the chain midway up the chain? And find out the tension in the chain at the point where the chain is attached to the ceiling.
