Question

A force of constant magnitude F and fixed direction acts on an object of mass m that is initially at rest. If the force acts for a time interval ∆t over a displacement ∆x , what is the magnitude of the resultant change in the linear momentum of the object?

Answer 1

Answer:

$\Delta P = F \Delta t$

Explanation:

As we know Newton's II law

$F$= Rate of change in momentum

so we will have

$F = \frac{\Delta P}{\Delta t}$

now we will have

$\Delta P = F \Delta t$

so here we can say that change in momentum of the object is the product of force and interval of time for which the force is acting on it.

so we will have

$\Delta P = F \Delta t$
