Question

A diver in a swimming pool bends his head before diving, because it: (A) decreases his moment of inertia (B) decreases his angular velocity (C) increases his moment of inertia (D) increases his linear velocity

Tardigrade Admin · Accepted Answer

When the diver bends his head, it decreases his moment of inertia. It results an increase in angular speed. Hence, it provides the diver more spin for fulfullest diver.

Q. A diver in a swimming pool bends his head before diving, because it:

decreases his moment of inertia

decreases his angular velocity

increases his moment of inertia

increases his linear velocity

When the diver bends his head, it decreases his moment of inertia. It results an increase in angular speed. Hence, it provides the diver more spin for fulfullest diver.
