Pulley (vertical disc): r = 0.33m, m = 4.00kg, initially at rest
Rope pulling (perpendicularly from side) with Force = F(t) = 3.00t - 0.20(t^2)
At t(in seconds) = 8, find linear speed of a point on the rim of the pulley.
Torque = R*F = 0.99t - 0.066(t^2) = 3.696 mN
From here, I don't know how to get either velocity or acceleration since rotational inertia is not given and acceleration is not constant.
I'm hoping someone can give me a little hint about what I'm missing and send me in the right direction.
Thank you
