Solution: The Great Sandini is a 60-kg circus performer who is shot from a cannon (actually a spring gun). You dont find many men of his caliber, so you help him design a new gun. This new gun has a very large spring with a very small mass and a force constant of 1300 N/m that he will compress with a force of 6500 N . The inside of the gun barrel is coated with Teflon, so the average friction force will be only 41 N during the distance of 5.0 m that he moves in the barrel.At what speed will he emerge from the end of the barrel, a distance 1.6 m above his initial rest position?
