A 60. kg student jumps from the 10. meter platform at ASU's swimming complex into the pool below.
a. Determine her Eg at the top of the platform.
b. How much Ek does she possess at impact?
What is her velocity at impact?
c. Repeat steps a and b for a 75 kg diver.
d. If she jumped from a platform that was twice as high, how many times greater would be her velocity at impact (compare to 60 kg woman)?
e. How much higher would the platform have to be in order for her velocity to be twice as great (compare to 60 kg woman at 10.m height)?
