While driving his pickup truck, Joe stops at a red light. When the light turns green, Joe steps on the gas and accelerates to 16 m/s in 4 seconds. What is Joe's acceleration?

================================================

Work Shown:

The values we're working with are

We'll plug those into the kinematics formula below to solve for 'a'

Joe's acceleration is 4 m/s^2

This means that every second, Joe's velocity is increasing by 4 m/s.

---------------------------

To check our answer, we can see that

Time 0 = Velocity 0

Time 1 = Velocity 4

Time 2 = Velocity 8

Time 3 = Velocity 12

Time 4 = Velocity 16

This confirms our answer.
