Question

a track player swings a 1.5 kg discus around at an arm's length of .8 m. if the discus is traveling at 3.0 m/s, what is its angular momentum?

Answer 1

Answer:

3.6 kg*m^2/s

Explanation:

The angular momentum equals mvr, where m is the mass, v is the velocity, and r is the radius or rotational arm. Inputting these values, we can find the angular momentum.

Angular momentum = (1.5 kg)(3.0 m/s)(0.8 m) = 3.6 kg*m^2/s

I hope this helps! :)
