A 20kg box rests on a rough floor. It takes a horizontal force of 40 N to keep the box sliding at a steady speed. Suppose a force of 100 N is applied to the box. What speed would thr box have after sliding for 3.0m?

    The net accelerating force is 60N.

    F=ma
    a= 60/20=3m/s^2

    Vf^2=Vi^2+2ad Vi is zero, you know a and d, solve for Vf
