•When two people push in the same direction on an object ofmass m they cause an acceleration of magnitude a1. When thesame people push in opposite directions, the acceleration of theobject has a magnitude a2. Determine the magnitude of the forceexerted by each of the two people in terms of m, a1, and a2.
