A 39.7-g bullet leaves a rifle and embeds itself in a 5.24-kg stationary block of wood. The wood-bullet combination flies away with a velocity of 2.4 m/s. What was the initial velocity of the bullet in m/s?

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).
