The following figure shows the relation between the applied force and the acceleration of an object while keeping the total mass constant. Given that the sum of the hanger mass and the added masses is m,+m, = 52 gm. Force versus acceleration 204 02 25 35 Acceleration (m) The mass of the cart is Select one: O a. 500 gm b. 212 gm c. 108 gm d. 448 gm
