Homework Statement

A 100 N force is applied with the help of the brakes of a 2000 kg car while the car is movign at 2.6 m/s speed. Two seconds later, the velocity of the car is

Homework Equations

a= F/m
v= vinitial - at

The Attempt at a Solution

a=100 N/2000 kg
a=.05

v=2.6m/s - .05(2)
v=2.6m/s - .1m/s
v=2.5m/s

So the answer is 2.5m/s. Am i going in the correct direction?
