## Homework Statement

A goalie moves in a straight line and her velocity is described by the graph shown. How far away is the goalie at the time t=2.0 from where she was at t =0?

The description of the velocity/time graph:

initial velocity is 3.0 m/s and increases to 4.0 m/s in 1.2 seconds (slope m =1/(1.2)). From 1.2 seconds to 2 seconds, the velocity decreases to 0 (the slope seems to be m= -2)

## Homework Equations

Displacement = area of undercurve.

## The Attempt at a Solution

I was given the graph, so i thought displacement would be to find the area under the lines...but apparently not.

I subtracted the area that forms the square and the triangle to find the displacement and got 2.6 m/s

**Can someone please tell me what I did wrong?! :(**
