Consider the ballistic pendulum we discussed in class, where a bullet of mass mb = 5 g is fired into a block of mass mB = 1 kg and gets lodged into the block. The bullet and block are then allowed to swing upward, reaching a final height of h. Here, however, instead of the block of being suspended by masses strings it is suspended by two thin rods of mass M = 0.5 kg and length 1 m.
(a) What is conserved in the collision, be specific?
(b) What is the angular-speed, w, of the ballistic pendulum right after the collision?
(c) To what height h will the ballistic pendulum swing up to?
(d) If the ballistic pendulum swing up to a height of h 5 cm, what is the initial speed of the bullet?

Alead ball is dropped into a lake from a diving board 5m above the water . it hits the water with a certain velocity and then sink with constant velocity in bottom . it reaches the bottom 5 second after it is dropped if g= 10m/s2 . find depth of the lake and average velocity of the ball ?
