A 0.0600 kg ball is traveling horizontally at 23.5 m/s when it is hit by a squash racquet. The ball then moves in the opposite direction, also horizontally, at a speed of 43.0 m/s. Take the initial velocity of the ball to be in the x-direction. What is the impulse delivered to the ball by the squash racket? (Give the x-component in N.s. Indicate the direction with the sign of your answer.
