The truck drives on a horizontal road with a constant velocity. It eventually halted by a set of crash barrels. The number of barrels and sand within the barrels are arranged in such a way to decelerate the truck at a constant rate. Four test runs are performed where the velocity and mass of the truck are varied. In each of the following situations, the barrels stop the truck in the same amount of time.
Which has the a. least force, b. greatest force.
