Plz now really important : ) 2. the following formula relates three quantities: force (f), mass (m), and acceleration (a). f = ma a. solve this equation for a. b. if the force is f = –25 units and the mass is m = 10 units, find the acceleration, a. c. if the force is f = 25 units and the acceleration is a = 5 units, find the mass, m.
