Q. 525.0( 1 Vote )

A diver having a moment of inertia of 60 kg-m2 about an axis through its center of mass rotates at an angular speed of 2 rad/s about this axis. If he folds his hands and feet to decrease the moment of inertia to 5.0 kg-m2, what will be the new angular speed?

Answer :

Given:


Angular speed (ω1) =2 rad/s


Moment of inertia (I1) = 60 kg-m2


Moment of inertia (I2) = 5.0 kg-m2


New angular speed (ω2) =?


Since external torque is zero
