If you jump barefooted on a hard surface, your legs get injured. But they are not injured if you jump on a soft surface like sand or pillow. Explain.
When we jump barefooted on a hard surface change in momentum occurs in a very small time so the force exerted by body is maximum and we get hurt. While in case of soft surface the change in momentum occurs in suitable amount of time, thus we don’t get hurt.

Two particles of masses m1 and m2 are joined by a light rigid rod of length r. The system rotates at an angular speed ω about an axis through the centre of mass of the system and perpendicular to the rod. Show that the angular momentum of the system is L = μ r2 ω where μ is the reduced mass of the system defined as

A uniform chain of mass M and length L is held vertically in such a way that its lower endjust touches the horizontal floor. The chain is released from rest in this position. Any portion that strikes the floor comes to rest. Assuming that the chain does not form a heap on the floor, calculate the force exerted by it on the floor when a length x has reached the floor.HC Verma - Concepts of Physics Part 1
