A force acting on an object given by the function F(x)=3x^2 + 4, where F is in Newtons and x is in meters. what is the change in the object's kinetic energy as it mores from x=1 to x=3 m?(adsbygoogle = window.adsbygoogle || []).push({});

W=6x

it changes from 6 J to 18 J

the answer 12 J is not the correct one

it says 26 J

why?
