## Homework Statement

I am just enquiring about car brakes, and figuring out how much force needs to be applied to stop a moving object (car).

## Homework Equations

1457Kg – Curb weight of the car (overall mass)

F = M x A

1457kg x 10mph = 14570 (Newtons)

1457kg x 20mph = 29140 N

1457kg x 30mph = 43710 N

1457kg x 40mph = 58280 N

1457kg x 50mph = 72850 N

1457kg x 60mph = 87420 N

1457kg x 70mph = 101990 N

## The Attempt at a Solution

So I've figured out the acceleration, but I need to find out, how much force needs to be applied to bring the car to a stand still using 312 Diameter brake disks. Would it be equal to or greater than the Acceleration?

Thank you for any help you may offer!
