V. Newton's 2 nd Law - The acceleration of an object is directly proportional to he force imparted on it and inversely proportional to the objects mass. Mathematically F = ma where F (force) is in Newtons (N), m (mass, is in kilograms (ky), and a (acceleration) is in meters per second squared :mis?). CL. The mass of a baseball is 0.145 kg and i's acceleration as i. falls to the ground is 9.81 m/2. How much force is a_ting on the baseball
