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

Starting at rest at the edge of a swimming pool, a 67.0 athlete swims along the surface of the water and reaches a speed of 1.15 by doing the work = 171 . Find the nonconservative work, , done by the water on the athlete.

2. Relevant equations

(m)(a)(x initial) + .5 (m)(v^2 initial) = (m)(a)(x final) + .5 (m)(v^2 final)

E=UK

W=Fd

F=ma

K=.5 mv^2

3. The attempt at a solution

Im not really sure how to tackle this problem those are the equations i think i need to use but should it go something like

K=.5(67kg)(1.15m/s^2) so K=44.3

E=UK (U being the work?) E= (171)(44.3) E=7575.3

i dont know what im doin i need some help that'd be great
