When the 5-kg block is 6 m from the wall, it is sliding at v1 = 14 m/s. If the coefficient of kinetic friction between the block and the horizontal plane is μk = 0.3, determine the impulse of the wall on the block necessary to stop the block. Neglect the friction impulse acting on the block during the collision.
