I missed my blog day on march 10. That day was the day after we pushed Mr. Finley's car. We went over the homework assigntment to start the period. The first answer were when the classmates pushed the car, the car sped up._.__.___.____. The second one was when nobody pushed the car, it moved at a constant rate.__.__.__.__.__. The third one was when Mr. Finley pushed the car, it slowed down, and then sped up. .________.______._____.____.___.__._.
After going over the homework, Connor sat on top of the cart while Josh pushed him. Josh easily pushed Connor. Then, Colleen sat on the cart next to connor. Josh had some difficulty pushing the two. Then, Kevin sat on the bottom of the cart. When Josh tried to push the cart, the cart didn't move. We concluded that mass was added each time another person was added so the cart didn't accelerate as much as when there was only one person.
