3 m from the origin. Hence, no force is acting on the particle. For 0 < t < 4 It can be observed that the given position-time graph has a constant slope. Hence, the acceleration produced in the particle is zero. Therefore, the force acting on the particle is zero. (b) At t = 0 Impulse = Change in momentum = mv – mu Mass of the particle, m = 4 kg

D) The table pulling upward on the Earth with force mg. 15) An object is moving with constant non-zero velocity. Which of the following statements about it must be true? A) A constant force is being applied to it in the direction of ... The greater the object’s mass, the greater its inertia and the larger the force needed to overcome inertia. Newton’s Second Law of Motion = The acceleration of an object by a force is inversely proportional to the mass of the object and directly proportional to the force. Force (N) = mass (kg) x acceleration (m/s 2) F = m a
