Question

Steven is doing interval training and runs at different paces throughout his 1-point workout. At times he runs at 0.5 m/s, other times he reaches a huge 3 m/s. If he begins his run at 0 m and ends it at 1000 m to the right, what is his average velocity if his run lasts a total of 500 seconds?

A) 0.5 m/s to the right
B) 3 m/s to the right
C) 2.5 m/s to the right
D) 5 m/s to the right

Answer 1

To determine Steven's average velocity over his interval training, we divide his total displacement (1000 m) by the total time taken (500 s), resulting in an average velocity of 2 m/s to the right, making option C the correct answer.

Step-by-step explanation:

The student asked about the average velocity of Steven who runs from 0 m to 1000 m to the right in 500 seconds. The average velocity is a vector quantity, which means it depends on both the total displacement and the total time taken. In this case, we use the formula:

Average velocity = Total displacement / Total time taken

Given that Steven starts running at 0 m and ends at 1000 m to the right (his total displacement is rightward 1000 m), and it takes Steven 500 seconds for the run, we can calculate his average velocity as:

Average velocity = 1000 m / 500 s = 2 m/s to the right.

Therefore, the correct answer is C) 2 m/s to the right.
