Answer:
ω₂ = 13.09 rad/s
Explanation:
given,
small disk rotating speed = 500 rpm
radius of small disk = R
radius of larger disk = 2 R
rotational speed of larger disk = ?
using the law of conservation of angular momentum, we get
I₁ ω₁ = I₂ ω₂
moment of inertia for solid disk
now,
ω₂ = 125 rpm
and
ω₂ = 13.09 rad/s
the rotational speed of larger disc is equal to ω₂ = 13.09 rad/s
