A carrom coin of radius 1.5 cm and mass 5 g strikes the side of the board at an angle 30^ with respect to the normal. The coin stays in contact with the side for 10⁻³ ~s and rebounds at an angle of 45^ with respect to the normal. The initial speed of the coin is 1 ~m / s and its final speed is 0.7 ~m / s . The average impulsive force on the coin in the normal direction is about
