A) The Figure below shows an illustration of a ballistic pendulum that is used for determining the velocity of bullets. The length L = 1.0 m and mass of the block A is M =10 kg. When a bullet of mass m = 38 g is fired into the block, the pendulum swings to angle 0 = 26 degree. Calculate the velocity of the bullet just before it embedded into the block. Assume that bullet stays lodged in block A and the mass of the rod length 1.0 holding block A is negligible. [Answer in m/s] b) Given that the velocity of a bullet of mass m = 40 g that enters the block A of mass 10 kg in Fig is 280 m/s and length L = 0.9 m, calculate the maximum angle 0 in degrees that the block A will swing to before swinging back down. [Answer in degrees]
