Homework Statement a disc drive at rest is powered up and accelerates according to alpha=alpha(i)sin(bt). this lasts for 1.66 seconds after which it no longer accelerates. alpha(i)=506 rad/s^2 b=1.89 radius of disc=3.9cm. After the disc is done spinning up what is the centripetal...

so if i understand you correctly, i just need to integrate to achieve my answer?

Homework Statement When powered up, a disk drive starts at rest and spins up with non-uniform acceleration. this lasts for 1.66 seconds after which it does not accelerate any more. how fast is it spinning at .87 seconds? alpha(i)=605 rad/s^2 B=1.89 Radius=2.03 cmHomework Equations...
