Part 1 is correct
Part 3 has the correct equation but the calculation is wrong. Check what you did on the calculator. It may help if you put brackets around the two numbers on the bottom.
Part 2.
You have already decided that the work done is equal to the loss in kinetic energy of the bullet in answering part 3 where you put work done (force x distance) = kinetic energy lost.
So is (b) just 3125J?
(C) is it 156250J?
