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: #3095.8J# (check my math though!)

Explanation:

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#).
Have a look:
