Find the work done by the force field F= 3yi - x^2j(adsbygoogle = window.adsbygoogle || []).push({});

in moving a particle along the curve y=x^(1/2) from (1,1) to (4,2)

so i parameterize and get x=1+3t, y= 1+t

so

3(1+t)-(1+t)^2

then take the derivative of x and y and multiple to ge

9(1+t)-(1+t)^2

and i integrate that from 0-1

and i get 13/2

but the answer should be 39/5

so my question is where am i going wrong
