Adisk with mass m = 5.7 kg and radius r = 0.43 m hangs from a rope attached to the ceiling. the disk spins on its axis at a distance r = 1.56 m from the rope and at a frequency f = 20 rev/s (with a direction shown by the arrow).

what is the magnitude of the angular momentum of the spinning disk?

Answer :

Explanation :

It is given that,

Mass, m = 5.7 kg

radius, R = 0.43 m

frequency, f = 20 rev/s

Angular momentum,

I is the moment of inertia of disk,

we know that,

so,

Hence, the magnitude of angular momentum of spinning disk is .

you cant move and you feel like someones pushing you down onto your bed it can feel like you want to get up but you just can't it can be extremely scary
