Question
initial question is: A 50g bullet traveling at 25.0m/s passes through a piece of wood block and exits at 22.0m/s. A high speed camera records the event. If the ball is within the wood block for 3.50ms, what is the average acceleration of the bullet during this time-interval??I have this part, find a.; However the next part says: "How thick is the wood block?" I need this equation, so I can plug in the numbers. I dont even know which one to begin picking out.. HELP please!! I have a test at 5 today!!

Explanation / Answer
given that intial velocity of the bullet is u=25 m/s final velocity of the bullet is v=22m/s the bullet is with in the wodden block for t=3.50ms=3.50*10^-3 s average accleraton of the bullet is a=v-u/t =857m/s^2 the thickness of the block is S=v^2-u^2/2a =0.0822m the thickness of the block is S=v^2-u^2/2a =0.0822mRelated Questions
