1.	A solid sphere has linear velocity v_(0)=4 m/s and angular velocity omega_(0)=9 rad/s as shown. Ground on which it is moving , is smooth . Itcollides elastically with a rough wall of coefficient of friction mu . Radius of the sphere is 1m and mass is 2 kg . If the sphere after colliding with the wall rolls without slipping on opposite direction, then coefdicient of friction mu is
