Question: A rifle bullet with a muzzle speed of 340m/s is fired directly into a special dense material that stops the bullet in 22.0 cm.
Part A: Assuming the bullet's deceleration to be constant, what is its magnitude?
I know the correct answer for above problem but explain how to get this answer! Thanks.
