Question

A man spinning in free space changes the shape of his body, eg. By spreading his arms or curling up. By doing this, he can change his.
A. moment of inertia
B. angular momentum
C. kinetic energy
D. angular velocity

Answer 1

Correct Answer - A::C::D
Angular momentum remain conserved & moment of inertia increases, from
`L = I omega, omega` will decrease and
`KE_("Rotational") = (L^(2))/(2 I), so, KE_("Rotational")` will increase.
