A constant horizontal force of magnitude F then acts on the box, accelerating it to the right. You observe that it takes the box $3\mathrm{.}4$ seconds to travel $13$ meters. What is the magnitude of the force F$?160$ N$4.$ A flatbed truck is carrying an $800-$kg load of timber that is not tied down. The maximum friction force between the truck bed and the load is $2400$ N$.$ What is the greatest acceleration that the truck can have without losing its load? $3\mathrm{.}0$ m$/$s~$5.$ A box of mass $72$ kg is at rest on a horizontal frictionless surface.
