A tennis ball of mass

0.060\,\text{kg}

strikes a rigid wall with a speed of

10\,\text{m\,s}^{-1}

and rebounds along the same line with a speed of

8\,\text{m\,s}^{-1}

. Taking the initial direction towards the wall as positive, determine the impulse imparted to the ball by the wall (give magnitude and sign).
