It consists of an initially stationary pendulum th moves after being struck by a bullet, and it is used to measure the original velocity of the bullet. The known variables are the bullet's mass m, the Pendulum's mass M and the height to which the block and bullet swing,determined by the length of the pendulum Land final angle 6 Assignment Status Click here fo detailed view ccXpertta.co A 100% Part (a) Two principles of physics are necessary to solve for the bullets original velocity.
