Anna walks off the end of a 10.0 m diving platform
a) What is her acceleration in m/s2 toward the pool?
b) how long does it take her to reach the water?
c) What is her velocity when she reaches the water?

Hints:

any thing falling freely has acceleration (due to gravity) = g

If u is initial velocity, a is acceleration, and s is distance travelled, the following quadratic
will you give you the time taken t, which must be a positve number!

s = ut + 1/2 at^2

If you know time t, initial velocity u, acceleration a, the following gives you final velocity v:

v = u + at


I hope the above helps.
