Given :
• A bullet leaves a rifle with a muzzle velocity =521m/s
• The bullet moves a distance =0.840m
To Find :
• The acceleration of the bullet =?
Formula :
Solution :
• We assume the bullet leaves from rest
So, the initial velocity will be ,u=0 m/s
•Also given, final velocity (v)=512 m/s
•Distance travelled (d) =0.840m
Let a be the acceleration of the bullet.
The acceleration of the bullet will be
