(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A 2500 kg car traveling to the north is slowed down uniformly from an initial velocity of 25 m/s by a 6240N braking force acting opposite the car's motion. What is the car's velocity after 2.52 s?

2. Relevant equations

F=m(Vf-Vi)/t

3. The attempt at a solution

This is how I used the equation

6240N=2500kg(Vf-25m/s)/(2.52s)

Solving for Vf I got 31.29m/s

The problem is that would mean the car's velocity is increasing, which it should be decreasing I think...
