A 60 kg circus performer who is shot from a cannon (actually a spring gun) the gun has a very large spring with a very small mass and a force constant of 1100 N m that he will compress with a force of 4400 N. The inside of the gun barrel is coated with Teflon,so the average friction forcewill be only 40 N during the 4.0 m he moves in the barrel. At what speed will he emerge from the end of the barrel,2.5 m above his initial rest position?
