this week in science we got proposed a new question from mr.segan and mr. finley. it was if we had a slow car and we had a fast car and we put them a few meters a away from each other, we would have to find out at what positoion are they going to hit. the experiment that my rable came up with was: we are going to do the same thing as we did with the walking experiment and find how many meters per seconds each car moves. after we get that info we can plot that on a chart and see where each one itrelocks which in real life would be were they crash. after we are done with the prediction we will go on test if the graph mathches the car in real life. my tables results was for the slow car it moved 7.13 seconeds per meter and for the fast car it moved 3.37 seconeds per meter. after that we thiiught it wwould be eaiser if we found out how far they would go in one minute so for the fast car it went .16 meters in one seconed. after we graphed the info we saw that they were going to crash at 13.43 seconed and four meters after we tested it out we saw that it was pretty close to what we predicted so the other time that was off was probably just a confounding variable.
