An ice skater is spinning at 2.5 revolutions per second and has a moment of inertia of 0.85 kg m2.
Estimate her rotational angular momentum, assuming for simplicity that she can be approximated as a rigid, axially-symmetric body.
Homework Answers
Here,
angular speed, wf = 2.5 rev/s
wf = 2.5 * 2pi rad/s
wf = 15.71 rad/s
moment of inertia, I = 0.85 Kg.m^2
rotational angular momentum = I * wf
rotational angular momentum = 0.85 * 15.71
rotational angular momentum = 13.34 Kg.m^2/s
the rotational angular momentum is 13.34 Kg.m^2/s

An ice skater is spinning at 6.8 rev/s and has a moment of inertia of 0.24 kg ⋅ m2. Calculate the angular momentum, in kilogram meters squared per second, of the ice skater spinning at 6.8 rev/s. He reduces his rate of rotation by extending his arms and increasing his moment of inertia. Find the value of his moment of inertia (in kilogram meters squared) if his rate of rotation decreases to 1.25 rev/s. Suppose instead he keeps his arms...
