## Homework Statement

A gun fires bullets each of mass 1g with velocity of 10m/s by exerting a constant force of 5 g weight. Find the number of bullets fired per second (take g=10 m/s2).

## Homework Equations

F=ma

M1U1 + M2U2 = M1V1 + M2V2 (conservation of linear momentum)

## The Attempt at a Solution

I am not sure why and how the concept of acceleration due to gravity is to be used here, are the bullets being fired vertically upwards? Any help is appreciated.
