A brick is sliding on a frictionless surface with the velocity vo→ and enters tangentially an area enclosed by a semi-circular fence with the curvature radius R. It then slides along the inner surface (without self-rotation). The friction coefficient between the brick and the fence is 4, and the size of the brick is much smaller than R. Determine the time required for the brick to escape the fenced area. Analyse the solution.
