# An object with a mass of 3 kg is pushed along a linear path with a kinetic friction coefficient of u_k(x)= 2e^x-x+3 . How much work would it take to move the object over #x in [1, 4], where x is in meters?

I found: $3095.8 J$ (check my math though!)
I used the integral version of Work due to the fact that the force depends upon $x$ (I also assumed the object moving at constant velocity along $x$).
