An object with a mass of #5 kg# is pushed along a linear path with a kinetic friction coefficient of #u_k(x)= 6x-1 #. How much work would it take to move the object over #x in [2, 3], where x is in meters?
See details in Explanation section
The question is similar to another question solved as bellow. The difference is in the value of coefficient of friction. Choose appropriate value and solve.
