A uniform disc of mass \(0.5 kg\) and radius \(r\) is projected with velocity \(18 m / s\) at \(t=0 s\) on a rough horizontal surface. It starts off with a purely sliding motion at \(t=0 s\). After \(2 s\) it acquires a purely rolling motion (see figure). The total kinetic energy of the disc after \(2 s\) will be \(J\) (given, coefficient of friction is 0.3 and \(\left.g=10 m / s ^2\right)\)https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
