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 1200 N/m that he will compress with a force of 6000 N. The inside of the gun barrel is coated with Teflon, so the average friction force will be only 45 N during the 5.0 m he moves in the barrel.

Problem 7.49
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 1200 N/m that
he will compress with a force of 6000 N. The inside of the gun barrel is coated with Teflon,
so the average friction force will be only 45 N during the 5.0 m he moves in the barrel.
Part A
At what speed will he emerge from the end of the barrel, 1.8 m above his initial rest position?
Express your answer in meters per second to three significant figures.
