A cylinder rotating at 4.3 rad/s is accelerated to 37.1 rad/s in 6.5 s. What is the angular acceleration of the cylinder? Give your answer in rad/s^2.

A strap, rod, or something comparable is used to spin up the disc.  I imagine someone hand-starting a lawnmower. If he pulls the strap with a final speed before pulling the strap away, what is the rotation rate of the disk, ω in rev/s?  The moment of inertia of a disc is 1/2MR2.  There's no sliding. Strap's final speed = v = 0.99 m/s. The disc's radius is R = 0.3 m The disc's mass is M = 0.8 kg
