Problem 10CQ

The force exerted by a diving board is conservative, provided the internal friction is negligible. Assuming friction is negligible, describe changes in the potential energy of a diving board as a swimmer dives from it, starting just before the swimmer steps on the board until just after his feet leave it.

QUESTION:

Problem 10CQ

The force exerted by a diving board is conservative, provided the internal friction is negligible. Assuming friction is negligible, describe changes in the potential energy of a diving board as a swimmer dives from it, starting just before the swimmer steps on the board until just after his feet leave it.

ANSWER:

Step 1 of 4:

        Consider a swimmer is standing on a diving board at the edge. Since the board has elasticity, the board gets deformed and the elastic potential energy is set up on the board. Assume that the frictional force acting is zero. Once the swimmer jumps up, the potential energy stored is converted into the kinetic energy. We are going to explain this here in detail how the potential energy is changing.
