What is a car’s acceleration if it increases its speed from 5 m/s to 20 m/s in 3 s? a: 5 m/s2 b: 15 m/s2 c: -15 m/s2 d: 10 m/s2

The formula for acceleration is:

a = (Vf - Vi) / t

Where:

a = acceleration

Vf = final velocity

Vi = initial velocity

t = time

(Note that the formula can also be written using V, Velocity, and V0, Velocity Nought/zero. Its the same as final and initial velocity, with initial being nought)

We have all we need to do the problem now:

Vf = 20 m/s

Vi = 5 m/s

t = 3s

a = (20 - 5) / 3

a = 5 m/s^2

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
