Reference no: EM13291826

A rifle shoots a 4.50g bullet out of its barrel. The bullet has a muzzle velocity of 965 m/s just as it leaves the barrel.

1. Assuming a constant horizontal acceleration over a distance of 40.0cm starting from rest, with no friction between the bullet and the barrel, what force does the rifle exert on the bullet while it is in the barrel?

2. How many g's of acceleration does the rifle give this bullet?

3. For how long a time is the bullet in the barrel?
