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)?

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
