The Great Sandini is a 60 kg circus performer who is shot from a cannon (actually a spring gun). You don't 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 3900 N. The inside of the gun barrel is coated with Teflon, so the average friction force will be only 33 N during the 3.0 m he moves in the barrel. Part A At what speed will he emerge from the end of the barrel, 2.0 m above his initial rest position? Express your answer in meters per second to three significant figures.
