A string is wrapped several times around the rim of a small hoop with radius r and mass m. The free end of the string is held in place and the hoop is released from rest.. (picture attached~)
So I tried using moment of inertia as mass*radius^2, so torque would be MR^2*alpha, and it would also be tension*R.
Solving for tension would give me mass*acceleration as tension.
Then net force would be tensionmass*gravity.
m*a=Tm*g
T=Tm*g
Now that doesn't make any sense.
Can anyone help?
