What is the acceleration of an object that goes from 3 m/s to 5 m/s in 8 s?

Acceleration formula is Vf-Vi divided by time. Final velocity = 5, Initial Velocity = 3, and time is 8.

So, do in a calculator (5-3) divided by 8.

Or step by step:

5-3 = 2

2/8 = 0.25

And units for acceleration is m/s/s (m/s squared) so it is 0.25m/s^2 (squared)

Answer: 0.25m/s2

Explanation:

Acceleration is change in velocity with time

V = final velocity = 5m/s

U = Initial velocity = 3m/s

t = time = 8s

a = Acceleration = ?

a = V - U / t

a = (5 - 3) / 8

a = 2/8

a = 0.25m/s2
