The spring of a spring gun has force constant k = 405 N/m and negligible mass. The spring is compressed 6.20 cm, and a ball with mass 25.0 g is placed in the horizontal barrel against the compressed spring. The spring is then released, and the ball is propelled out the barrel of the gun. The barrel is 6.20 cm long, so the ball leaves the barrel at the same point that it loses contact with the spring. The gun is held so he barrel is horizontal. What is the greatest speed the ball have along the barrel if a constant resisting force of 6.70N acts on the ball as it moves along the barrel? (Your result must be in units of m/s and include 2 digit after the decimal point. Maximum of 3% of error is accepted in your answer.)
