A 550 g basketball in flight has a velocity of 4.18 m/s [W] at the top of its arc. At that point it is struck by a 58.4 g arrow flying north at 38.2 m/s. The arrow becomes lodged in the ball. Based on the information in the above narrative, if the average net force the bow exerted on the arrow to get it to that speed was 85.2 N, how long was the force exerted on the arrow by the bowstring?
