Two students are conducting an experiment in which they are trying to find a relationship between the angle of incline of a ramp and the final speed a car reaches when rolling down the ramp. In order to collect their data, the students must determine the final speed of the car at the bottom of the ramp. The students discuss how they should determine this speed. Student 1: “We need to measure the length of the ramp and the time it takes the car to roll down it. Then we can divide the total distance by the total time to find the final speed.” What is wrong with Student 1’s method for determining the final speed? This method will only determine the average speed, not the final speed. This method will determine the acceleration, not the final speed. This method does not account for the height of the ramp. This method does not take into account the angle of the ramp.
