# Swinging balls

**Classical Mechanics**Level 2

a) Right after the collision between the ball \(A\) and ball \(B\), the ball \(G\) flies to the height of \(h\) to the right.

b) If we pull back the balls \(A\) and \(B\) to the height of \(h\) to the left and allow them to strike the line, then the ball \(G\) flies to the height of \(2h\) to the right.

c) If we pull back the balls \(A\), \(B\) and \(C\) to the height of \(h\) to the left and the balls \(F\) and \(G\) to the height of \(h\) to the right, and allow them to strike the line simultaneously, then the ball \(D\) will not move.
