Consider a solid ball (sphere) of uniform density. Its radius is 10 cm and mass is 0.1 kg. What is the ball's moment of inertia if it is rotating about its center? Enter in a numerical answer. Assume the SI base units of moment of inertia (but do not enter the units and do not use scientific notation).

Agymnast dismounts off the uneven bars in a tuck position with a radius of 0.3m (assume she is a solid sphere) and an angular velocity of 2rev/s. during the dismount she stretches out into the straight position, with a length of 1.5m, (assume she is a uniform rod through the center) for her landing. the gymnast has a mass of 50kg. what is her angular velocity in the straight position?
