Question

A net force of 100 N is applied to a wagon for five seconds. This causes the wagon to undergo a change in momentum of

Answer 1

Answer:

500 Ns

Explanation:

According to the impulse theorem, the change in momentum of an object is equal to the impulse exerted on it. Mathematically:

$\Delta p = I = F \Delta t$

where

$\Delta p$ is the change in momentum of the object

I is the impulse exerted, which is the product of

F, the net force exerted

$\Delta t$, the time interval during which the force is applied

In this problem,

F = 100 N is the force applied on the wagon

$\Delta t=5 s$ is the time interval

Substituting, we find the change in momentum of the wagon:

$\Delta p = (100)(5)=500 Ns$
