A golf club strikes a 0.049-kg golf ball in order to launch it from the tee. For simplicity, assume that the average net force applied to the ball acts parallel to the ball’s motion, has a magnitude of 6130 N, and is in contact with the ball for a distance of 0.013 m. With what speed does the ball leave the club
