WebIn the equation V = d/t, V is the velocity, d is the distance, and t is the time. Determine the object’s acceleration by dividing the object’s mass by force and multiply the answer by the time it took for it to accelerate. For example, if the object weighs 30 kg and has a force of 15 N applied to it, then the acceleration would be 4 m/s.
