One can measure the speed v of a bullet by using a ballistic pendulum. Let the mass of the bullet m-8g. The mass of the wooden pendulum is M-8 kg. The bullet is shot, and the system made of Wood+ Bullet starts swinging with the initial velocity V upward, as much as h-5 cm. a) (10 p) Via using the law of energy conservation and the law of linear momentum conservation, find the initial velocity of the bullet, in terms of M, m, h and the Earth's acceleration g. b) (10p) Calculate v. Take g=10m/s One can measure the speed v of a bullet by using a ballistic pendulum. Let the mass of the bullet m-8g. The mass of the wooden pendulum is M-8 kg.
