    Distance traveled by a block due to unbalanced force

    Homework Statement A 60 N block in horizontal plane is pushed horizontally by force P = t^3 + 10t. The frictional resistance f = 6 - t^2. What is the distance traveled by the block after 2 seconds. Homework Equations The net force F = (t^3 + 10t) - (6 - t^2) = t^3 + t^2 + 10t - 6. The...
