## Homework Statement

I was given this worksheet today:

http://www.mrwaynesclass.com/impulse/WS/momentum.pdf

However, I was not in school today nor when we started momentum. So I'm a little confused with the graphs. On a force versus time graph, how do you go about solving for velocity? An example problem would be #37. They give you the answer to be -1 m/s (answers are at the bottom) but how do you get there?

## Homework Equations

P=mv

ΔP/ΔT = F

F=ma

## The Attempt at a Solution

I figured that impulse (ΔP) would be area under the curve, so I calculated that. But using the force and time on the graph, the impulse didn't match up and I just got all confused and frustrated. Can anyone help?
