The speed of a bullet is 300. m/s as it emerges from the 1.00-meter-long barrel of a rifle. assume that the acceleration of the bullet is constant along the entire length of the barrel, and that the bullet started from rest. what is the acceleration, a, for the bullet while it is in the barrel? (hint: time doesn’t matter in this part. think about which kinematics equation to use.
