What is the velocity of the car

  1. Oct 30, 2008 #1
    1. The problem statement, all variables and given/known data
    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

    2. Relevant equations
    a= F/m
    v= vinitial - at

    3. The attempt at a solution
    a=100 N/2000 kg

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

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