Question

A solid sphere has linear velocity
Vo = 4 m/s and angular velocity
F
4
0 =9rad/s as shown. Ground on
which it is moving is smooth. It
collides elastically with a rough wall
of coefficient of friction H. Radius of
the sphere is 1m and mass is 2kg
Vo
If the sphere after colliding with the
wall rolls without slipping in opposite
direction, then coefficient of friction u
is​
