VAY, Vox, Vay in the laboratory frame of Problem 3-Conservation of angular momentum and physical pendulum A system is composed of a thin uniform rod of length L = 1 m and mass M = 1 kg, and a bullet of mass mb = 7 g. Initial, the rod is in equilibriur force of gravity, with its axis along the vertical direction, pivoted at a distance L/4 from the rod's upper end; the bullet travels along the x-di initial velocity v = 100 m/s, until it collides against the rod at a distance 1/4 from the rod's lower end. After the collision, the bullet emerges with a velocity v' = 50 m/s along the x-direction, and the rod starts rotating around its pivot point. (a) Find the initial angular velocity of the conservation of energy to find the maximum angle reached by rod. (c) Find the time it takes for the rod to return to its original position, in the the maximum angle reached by the rod is small (Hint: in part b, use 1- cos a = 2 (sin a/2)² ). the bottom.
