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 strike during collision if its moves perpendicular to the edge is (all collisions the elastic)
