igh = mv² %3D V = 2gh KE 11. A bullet of mass 2 grams, travelling at 500 m/s is fired into a ballistic pendulum of mass 1 kg suspended from a cord 1 m long. The bullet penetrates the pendulum and emerges with a velocity of 100 m/s. Through what vertical height will the pendulum rise? RELATIONSHIP BETWEEN WORK AND ENERGY Theory: The net work done on an object always produces a change in kinetic energy of the object. Vo Total work done = AKE Positive work - Negative work = KE final - KEinitial mv² 2 mvo P(S) - F(S) = 2. 12. What average force is required to stop a bullet of mass 20 grams and speed 250 m/ s as it penetrates wood to a distance of 12 cm? NEWTON'S LAW ON ANGULAR MOTION Theory: An unbalanced torque about an axis produces an angular acceleration, about that axis, which is directly proportional to the torque and inversely proportional to the rotational inertia of the body about the samne axis.
