Question

A racecar is equipped with a computer that records the reading on its speedometer every second during a race. If you graph this data, what will be the best choice for the dependent variable?

a. time
b. position
c. average velocity
d. instantaneous velocity

Answer 1

Because it records speed of the car at a certain time, the independent variable should be time and dependent would be speed or velocity. Since it's taken every second, it would be considered instantaneous velocity, which is D.
