1.	A solid sphere linear velocity V_(0)=4m//s and angular velocity omega_(0)=9 rad/s as shown. Ground on which it is moving is smooth. It collides (e=1) with rough wall of coefficient of friction mu. Radius of sphere is 1m and mass is 2kg.
Answer» If the sphere ROLLS without SLIPPING after collision, `mu=0.25` Angular velocity after collision is 4 rad/s clock WISE Angular velocity after collision is 4 rad/s clock wise If the sphere rolls without slipping after collision, `mu=0.5` ANSWER :A::B
