Question

students conduct an experiment in which they roll a marble down a ramp. they want to find the final speed of the marble. if they have the total distance the marble roll and the time it took to roll back distance, can they find the final speed of the marble?

Answer 1

Yes, the students can find the final speed of the marble given the total distance rolled and the time it took to roll back that distance.

To do this, they can use the formula for average speed:

average speed = total distance / total time

Since they want to find the final speed, they need to use the total distance rolled and the time it took to roll back that distance (which would be the total time).

However, it's important to note that the average speed is not necessarily the same as the final speed in this experiment. Rolling a marble down a ramp might result in an initial acceleration that affects the final speed. So, while the students can use the average speed as an approximation, it might not accurately represent the final speed of the marble.
