Homework Statement
Homework Equations
I = 1/2 mR^2
Ug = mgdsinθ
Us = 1/2 kd^2
KE = 1/2 I w^2
The Attempt at a Solution
Moment of inertia of reel = 1/2mR2
Kinetic energy of the reel = 1/2 mv2 = 1/2(1/2mR2) w2
KE = mgdsinθ (potential due to gravity) + 1/2kd2 (spring potential)
w = sqrt(4(mgdsinθ + 1/2kd2) / mR2)
This answer is incorrect, I'm wondering where I went wrong. Please help if you are able to. Cheers!
