Today's objectives: 1. First we started by doing daily question that was about a small car and a big car hitting each other with the same speed, we had to find out what would be the difference between the cars after the collision. It was multiple choose question. The answer was the speed of the big car would be greater then the small car. 2. There was also another question about three cars stopping in different times since we didn't know the mass we had to say that they were the same and the was no difference between them.

We recieved a lab having to do with collision. The lab was about Ken and Barbie riding there bumper cars on a fricionless surface. Before Mr. manning let us work on it he demostrated a couple of questions and solve them by using the formula V=x/t=xf-xi/tf-ti. For example both Ken's and Barbie's mass were the same but different velocities. Ken was at rest while Barbie was at 5m/s. Ken's speed increase while Barbie's decreased and stopped. After his directions we had to make a table graph by plugging in the imformation that was given into a website that was given to us.

The picture below is for 1.
