Homework Statement
Homework Equations
I_solidcylinder = .5mr^2
I_thinring = mr^2
torque = I*Ω (where Ω = angular acceleration)
change in theta = .5(Ω)(time^2)
The Attempt at a Solution
Attempted to solve for angular acceleration:
(2.5)(9.8)(0.1) = (3*0.25^2 + 0.5*4*0.1^2)Ω
Ω = 11.8 rad/s/s
which I then plugged into the rotational kinematics formula:
Δ∅ = 0.5*11.8*0.5^2
which gave me a wrong answer. Where'd I go wrong?
