(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A high diver of mass 50.0 kg jumps off a board 10.0 m above the water. If her downward motion is stopped 2.30 s after she enters the water, what average force did the water exert on her?

2. Relevant equations

F_{net}=ma

v_{f}^{2}=v_{0}^{2}+2ax

3. The attempt at a solution

First I found the final velocity of the diver when she hits the water

v_{f}^{2}=0^{2}+2(9.8)(10)=196

v_{f}=14 m/s

Since she is slowed to a stop in 2.3s the average acceleration would be

14/2.3 = 6.08696

Knowing acceleration and her mass, we can calculate the force.

F=50(6.08696)=304.348

This answer was marked wrong. I'm pretty sure I did everything right. Am I missing something?
