Q1) AT the conclusion of his competition routine, an ice-skater spins in one spot
at a rate of 4.8 rotations per second. If you assume that his moment of inertia is
0.75 kg. m>, what is his angular momentum? At the conclusion of
the spin, the skater slowly and dramatically slows to a stop over 1.5 s by
dragging the toe on one skate.
a) What was the value and sign of the angular impulse on the skater?
b) What average torque did the ice exert on the skater?
