Conservation of angular momentum
I1 * omega 1 = I2 * omega2
129 * 95 = 32 * new RPM
by the way
n RPM -> n revs/min * 1 min/60 s * 2 pi rad/rev = n* (2 pi/60) rad/s
I don't understand this: Russian ice skater, Alina Zagitova, spins her way to projected Gold in the 2018 Olympics. During one particular spin, she moves from a camel spin that rotates at about 95. RPM to a
tight spin. If her rotational inertia changes from 129kgm² to 32kgm², what is the final spin rate of Miss Zagitova in rad/s and RPM?
Where do I insert the factors and into which equations?
