Question

A disk is attached by a spring to a pin. The disk can roll in the horizontal direction and the pin is above it.

 

The spring has an unstretched length of .5m and a spring modulus of 600 N/m

 

THe disk has a mass of 20kg and a radius of 200mm

 

The center of hte disk is 600mm below the pin and 320mm to the side (so the spring starts diagonal)

 

If the spring is released, what is the speed of the disk when the spring is perfectly vertical? Assume the disk does not slip and is free to spin
