Answer 1

The change in momentum of a body is known as impulse

Explanation:

The change in momentum of a body is called impulse delivered to that body. It is given by :

$J=mv-mu$

$J=p_f-p_i$

Here,

v is the final speed

And u is the initial speed

It is also defined as the impact of force on a body. If t is the smallest time of constant, then the impulse is given by :

$J=F\times t$

Hence, this is the required solution.
