The size of force slowing the car down is 22.2 m.
What is acceleration due to friction?
The formula is a = F/ m.
This comes from Newton's Second Law.
Like we know that friction is included here, we need to derive the formula according to the situation, a = (F – Ff) / m. Here friction will accelerate the object more.
The force of static friction is what pushes your car forward.
The engine provides the force to turn the tires which, in turn, pushes backwards against the road surface.
