1. The problem statement, all variables and given/known data So I have a block that has had a bullet shot through it at an initial speed of 280m/s. It is 0.03kg and after it leaves the block it is travelling at 190m/s. The block is a length of 0.012m and weighs 1.50kg. What is the average force exerted on the block? 2. Relevant equations ek=0.5mv2 f=ma 3. The attempt at a solution I have no idea what I'm doing. I found the first part of the question, which was the change in kinetic energy.
