The coefficient of restitution between a snooker ball and the side cushion is 13. If the ball hits the cushion and then rebounds at right angles to its original direction, then what is the angle made with the side cushion by the direction of motion before and after impact?
  1. tan -1 1 3
  2. tan-13
  3. cot -1 3
  4. cot -1 1 3

Solution



coefficient of restitution = 1 3

u cosθ=v sinθ ... (1)

v cosθ=u3sinθ ......(2)

From (1) and (2)

tan2θ=3

θ=tan-13
