He 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 3600 N. The inside of the gun barrel is coated with Teflon, so the average friction force will be only 49 N during the 3.0 m he moves in the barrel.
Required:
At what speed will he emerge from the end of the barrel, 2.5 m above his initial rest position?

It is reasonable to assume that the bulk modulus of blood is about the same as that of water (2.2 gpa). as one goes deeper and deeper in the ocean, the pressure increases by 10000 pa for every meter below the surface. if a diver goes down 80.0 m in the ocean, by how much does each cubic centimeter of her blood change in volume? give the answer in cubic centimeters (actually one cubic centimeter equals one milliliter).
