## Homework Statement

As simple as the question may seem, I require some honest help. I'm particularly new to physics.

The question is the following:

A net force of magnitude 4.0N acts on a body of mass 3.0kg for 6.0 s. The body is initially at rest.

Which of the following is the speed of the body after the 6.0s interval?

## Homework Equations

a = Fnet / m

Fnet = m • a

**1 Newton = 1 kg • m/s^2**

## The Attempt at a Solution

[/B]

I came across this question while browsing some IB tests online for High Level physics and decided to try to solve some of them. Looking at this one, I researched the equations necessary but can't find out how to calculate a net force using only force exerted, mass, and time. On the other hand, I can solve it with both mass and acceleration.

Any tips or equations I haven't found yet? Thank you.
