Homework Statement
a hoop of mass m and radius r has a cord wrapped around it the hoop is released while holding the string the hoop rolls without slippage
write out force and torque eqns on the hoop
given m, r determine downward accel
Homework Equations
Torque = I alpha
Torque = r x F
The Attempt at a Solution
Torque = I * alpha
I of hoop = m*r^2
alpha = r*a
r x F = m*r^3 * a
this F must have relationship to gravity and tension right? if it were ma then my as cancel
Fy should be ma = Tension - mg ?
im lost at this point, thanks for any help
