Question

A runner maintains a constant velocity of +3.0 m/s. Which of the following position-time graphs shows the runner’s location from the starting point at 5.0 s intervals for 30.0 s?

Answer 1

since the runner maintains a constant velocity of +3.0 m/s. to solve the runner’s location from the starting point at 5.0 s intervals for 30.0 s we must use the equation rt = d
where r is the velocity
t is the time
d is the distance
d = (3 m/s) ( 30 s)
d = 90 m
