A ball hits 2 walls which wake an angle alpha with each other. If the initial trajectory makes an angle beata with the first wall how mang times will the ball hit the first wall? Pick values for alpha and beata such that the ball hits the first wall 4 times. Explain all your computatious. If we want the ball to be able to hit line 1 n times how small has alpha need to be. (Write alpha in terms of n). To understand the direction of a line you can replace it by any line parallel to the line. We want an inequality for alpha and beta. Also note 2 reflection rotation by twice the angle. Please draw a diagram too
