Problem 23CQ

Competitive divers pull their limbs in and curl up their bodies when they do flips. Just before entering the water, they fully extend their limbs to enter straight down. Explain the effect of both actions on their angular velocities. Also explain the effect on their angular momenta.

Step-by-Step Solution:

Step-by-step solution Step 1 of 2 Before entering the water, the divers pull their limbs in and curl up their body. Doing so, they gain angular momentum along the centre of mass of the body, the gravitational force acting on the center of mass exerts toque on the body and increases the angular velocity and hence the rotational kinetic energy as well as angular momentum increases.

Step 2 of 2
