The following data was collected from an experiment in which students observed four cars go from 0 km/hr. to 60 km/hr.
Car Number
Time (s)
1
2.5
2
4.2
3
5.2
4
3.3
Based on the data collected, which of the following quantities would be best for the
comparison of the cars?
a. Stopping distance, because each car will have a different distance it will travel as it
slows down and that distance can be calculated using the average velocity
equation.
b. Instantaneous speed, because the students already know that each car is going 60
km/hr.
Average acceleration, because the change in velocity and time can be used to
calculate the average acceleration using the average acceleration equation. indows
machine was
d. Stopping time, because each car should stop in the same amount of time that it took
the car to reach 60 km/hr.
