If you placed a cylinder with a 0.25 m radius in the middle of a record player that spins at 4.7 rad/s, what is its angular momentum? the cylinder has a mass of 2.0 kg.

0.29 kg m² / s

Explanation:

Angular momentum is the product of moment of inertia and angular velocity.

L = I ω

For a solid cylinder, I = ½ m r².

L = ½ m r² ω

L = ½ (2.0 kg) (0.25 m)² (4.7 rad/s)

L = 0.29 kg m² / s
