Ayo-yo is made from two uniform disks, each with mass m and radius r, connected by a light axle of radius b. a light, thin string is wound several times around the axle and then held stationary while the yo-yo is released from rest, dropping as the string unwinds. find the linear acceleration and angular acceleration of the yo-yo and the tension in the string.

linear acceleration

angular acceleration

Explanation:

As we know that the force due to tension force is upwards while weight of the disc is downwards

so we will have

also we have

now we have

now we have

so we have

linear acceleration

angular acceleration
