A bullet is fired from a gun, the force on the bullet is given by where F is in newton and t in second. The force on the bullet becomes zero as soon as it leaves the barrel. What is the average impulse imparted to a bullet?
Step 1: Given data
Step 2: Concept and formulae
Step 3: Finding the average impulse of the bullet
The force exerted on the bullet is,
.
Now let's say at time T the bullet leaves the barrel. And we know outside the barrel exerted force on the bullet is zero.
So,
Now, the impulse imparted by the bullet is,
Therefore, the average impulse imparted by the bullet is
