## Homework Statement

Consider the Olympic sport of diving. The more time the athlete spends in the air, the greater the potential to complete difficult maneuvers. Off of a 3m spring board with a stiffness of 5920N/m, a diver with a mass of 52kg will maximally deflect the board 0.5m from it's equilibrium position. Assume that all of the strain energy stored in the boards returned to the diver in the vertical direction.

a) How much time will the diver be in the air when using the 3m spring board?

b) What will the diver's velocity be when they hit the water?

c) How much time will a diver spend in the air when diving off of a 10m platform?

d) What will the diver's velocity be when they hit the water?

Sorry for putting a photo in, if you can't make it out let me know and I'll type it out!

Since the velocities ended up being the same I think I may have gone about it the wrong way...
