Question

An ice skater has a moment of inertia of 4.6 kgm2 when her arms are outstretched. at the time, she is spinning at 2.4 revolutions per second (rps). what is her angular momentum?

Answer 1

The angular momentum of the ice skater is 11.04 kgm²/s.

Step-by-step explanation:

Angular momentum is given by multiplying the moment of inertia (I) and the angular velocity (ω). To find the angular momentum of the ice skater, you can use the formula:

Angular momentum = I x ω

Given that the moment of inertia of the ice skater is 4.6 kgm² and the angular velocity is 2.4 revolutions per second (rps), you can substitute these values into the formula to find the angular momentum:

Angular momentum = 4.6 kgm² x 2.4 rps

Calculating this, you will find that the ice skater has an angular momentum of 11.04 kgm²/s.
