Question

How do I calculate the bullet’s speed in m/s?

Answer 1

Hint : In this question we have to find the process to find the speed of a bullet. For this first we will consider some parameters for bullets. Then we will see the process to find the speed of the bullet. If the target is rotating then we will consider this rotation in calculation.

Complete step by step answer:
Let the speed of the bullet is v, d is the distance covered by the bullet and ϴ is the angle by which the target is rotating.
First we will find the time taken by the bullet from one place to another. This time will be equal to the time taken by the bullet to rotate by a given angle ϴ.
So, the velocity of the bullet is given by $t = \dfrac{d}{v}$
We will find the time taken using the angle of rotation. Then we will equate both times to find the speed of the bullet.
Result- Hence, from the above explanation it is clear that we can easily find the value of speed of bullet in m/s.

Note- Hence, from the above explanation we can see that finding the value of velocity is quite easy. It is just using the general formula of time. If the target is rotating then we will consider the angle of rotation in the calculation. If the angle of rotation is given in rad/sec then first we will convert this angle into degrees then we can use it in the formula to find time because time taken in rotation is equal to the time taken by the bullet to go from one place to another place.
