Question

An impulse J is applied on a ring of mass m along
a line passing through its centre O. The ring is
placed on a rough horizontal surface. The linear
velocity of centre of ring once it starts rolling
without slipping is​

Answer 1

Answer: J/2m

Explanation:

Apply newton rotational equation,torque equation,Change in momentum which is impulse.

In the image, v is velocity of center

                      $v_{p}$ is velocity of point p

                      $v_{o}$ is velocity of com
