Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.

Question

A strap, rod, or something comparable is used to spin up the disc. T 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, w in rev/s? The moment of inertia of a disc is 1/2MR?.
There's no sliding.
• Strap's final speed = v = 0.74 m/s.
• The disc's radius is R = 0.7 m
• The small disc's radius is 1 cm
• The disc's mass is M = 0.7 kg
