In a carom-board game the striker and the coins are identical and of mass $m$ . In a particular hit the coin is hit when it is placed close to the edge of the board as shown in figure such that the coin travels parallel to the edge. If the striker is moving with speed $v$ before the strike, then the net impulse on the striker during collision if it moves perpendicular to the edge after collision, is (assume all collisions to be perfectly elastic)
