A uniform circular disc of mass 2 m and ...

A uniform circular disc of mass 2 m and radius R placed freely on a horizontal smooth surface as shown in the figure- 5.116.A particle of mass m is connected to the circumference of the disc with a massless string. Now an impulse J is applied on the particle in the directions shown by dotted line. The acceleration of centre of mass of the disc just after application of implues is `("If J "= 10 N -sec ., m=sqrt10 kg and R= 25cm )`
