2. A diver with a mass of 70.0 kg
stands motionless at the top of a
3.0-m-high diving platform.
Calculate his potential energy
relative to the water surface while
standing on the platform, and his
speed when he enters the pool.
(Hint: Assume the diver's initial
vertical speed after diving is zero.)

Part 1: a magnetic levitation or maglev train rides rails without touching them. explain how this works using your data. include the appropriate magnet drawing in your answer. part 2: two objects are near a bar magnet. one is about 1 cm away, while the other is 6 cm away. compare and contrast the magnetic force that affects each object. use your data to answer the question
