Joe go is able to run at constant acceleration for several seconds. if he starts from rest and after 4 sec is traveling at 8.0 m/s, what was his acceleration?

The acceleration of Joe as he ran at constant acceleration is 2m/s².

Given the data in the question;

Since Joe starts from rest,

Acceleration;

To determine the acceleration, we use the First Equation of Motion:

Where v is final velocity, u is initial velocity, a is acceleration and t is time taken.

We substitute our given values into the equation

Therefore, the acceleration of Joe as he ran at constant acceleration is 2m/s².
