so…u think u can solve this…?
A billiard table with dimensions 101×200 has pockets only at its corners. A ball rolls out of a pocket and moves along the angle bisector of the angle made by the sides, reflecting from the sides of the table (obeying the usual laws that angle of incidence = angle of reflection). Is it possible for it to go into a pocket again?
add some details…
also i confirm that the pockets are only at the CORNERS…
It only possible only when gravitational force, when the ball reaches the pocket acting on it greater than the force of re-bounce when it hits the corner of the pocket.
If the gravitational force is greater when it reaches the pocket will fall in the pocket.
