A child jumps on a trampoline. He stretches the trampoline downward when he lands on it. He comes to a short stop when the trampoline can't stretch any farther. He then bounces upward again. What is happening to his kinetic energy as the trampoline stretches and slows him? His gravi- tational potential energy? The elastic potential energy of the trampoline? What is happening to the total of these three?

Which diagram correctly demonstrates the various forces acting on a ball moving horizontally with some speed?

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).

The force needed to overcome static friction is usually less than that needed to overcome kinetic friction.true or false?
