Answer:
12500(kg*m/s)
Explanation:
F=ma=mv/t=p/t
p=F*t=500N*25 s=12500(kg*m/s)
They have different accelerations because of their masses. According to Newton's Second Law, an objects acceleration is inversely proportional to its mass. Therefore the object with the larger mass, in this case the gun, will have a smaller acceleration. In the same way, the less massive object, being the bullet, will have a higher acceleration.
Hope this helps :)
