Results for "'a uniform solid sphere of radius r is rolling on a smooth horizontal surface'"
A uniform solid sphere of radius r is rolling on a smooth horizontal surface with velocity V and angular velocity omega (where V=omega r). The sphere collides with a sharp edge on the wall as shown in the figure. The coefficient of friction between the sphere and the edge mu=1/5. Just after the collision the angular velocity of the sphere becomes equal to zero. The linear velocity of the sphere just after the collision is equal to :Vdfrac {V}{5}dfrac {3V}{5}dfrac {V}{6}
