2. A 6.0 kg body moving at a speed of 4.0 m/s collides with a body twice its weight and moving at half its speed along the same direction. After the collision, the 6.0 kg body moves in the opposite direction with a speed of 2.0 m/s. Find
the final velocity of the heavier body [A] 3.0 m/s [B] 36.0 m/s [C] 5.0 m/s [D] 12.0 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).
