A toy truck with a mass of 0.67 kg is moving to the right with a velocity of 5.1 m/s when it strikes a toy car that has a mass of 0.15 kg and is also moving to the right. If, after the collision, the velocity of the truck is 4.2 m/s to the right and the velocity of the car is 4.6 m/s to the right, what was the initial velocity of the car?

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).
