A bullet of mass 60g is fired into a 20kg block of wood which is suspended on a light inextensible wire to form a ballistic pendulum. After penetration the bullet remains in the wood. The vertical position of the wood-bullet combination increases by 28cm. Calculate the velocity of the bullet?
I know that you will have to use conservation of momentum here... However I am unsure of how i am going to do this with the given information. Ant tips? thanks
