Question

A student is trying to determine how fast they can run by calculating their averagevelocity. The student runs 27.00 meters in 2.50 seconds. What is the student'saverage velocity in meters/sec?

Answer 1

ANSWER

10.80 m/s

EXPLANATION

Given:

• The student's displacement, Δx = 27.00 m

,

• The time it took the student to run that distance, Δt = 2.50 s

Find:

• The student's average velocity, v

The average velocity is given by,

$\bar{v}=\frac{\Delta x}{\Delta t}$

Substitute the known values and solve,

$\bar{v}=\frac{27.00m}{2.50m}=10.80m/s$

Hence, the average velocity of the student is 10.80 m/s.
