Work integration
A 3.8 kg block is acted upon by a horizontal force F(x) = 24.0 -4.0x where the force is measured in Newtons if x is measured inmeters. The coefficient of kinetic friction between the block andthe flat surface is 0.19. The block is initially at x = 0 m. Whatdistance must the block travel if the net work done on the block byF(x) and friction combined is to be exactly zero? At what pointwhat point along the way does the net force on the block reachzero?
