## Homework Statement

A force acts on an object of mass .425kg. The force varies with position as shown in the graph that follows.. (Force Y-axis, Position x-axis). Find the work done by the force in moving the object from .40m to 1.20m. The two points are (.40m, 1.6N) and (1.20m, 2.2N)

## Homework Equations

Integral of f(x) dx from a to b = work

## The Attempt at a Solution

How do I find the equation of the curve from the two points to integrate it?? Is the mass relevant?
