By Newton's 2nd law Force applied is proportional to the rate of change of momentum which varies with mass and acceleration of the object being fired. So in the case of a bullet, You have more mass compared with air and hence it can create a force (F=ma) which will penetrate the body which is not the...

Sameer went on his bike from Delhi to Gurgaon at a speed of 60km/hr and came back at a speed of 40km/hr. What is his average speed for entire journey?
To find the average speed, you need to know the formula of average speed. The avg speed 0= 2 d / (t1+ t2) = 2 v1.v2/(V1 + V2). Just substitute the value.
