(a) Calculate the angular momentum (in kg.m/5) of an ice skater spinning at 6.00 rev/s given his moment of inertia is 0.370 kg.m. kg-m/s (b) He reduces his rate of spin (his angular velocity) by extending his arms and increasing his moment of inertia. Find the value of his moment of inertia (in kg-m2) if his angular velocity drops to 1.70 rev/s. kg.m (c) Suppose instead he keeps his arms in and allows friction with the ice to slow him...
