MOCO anyone

  1. Oct 14, 2008 #1
    1. The problem statement, all variables and given/known data

    A 4200lb vehicle is cruising down the highway at 65mph when the driver steps on the brake applying a braking force of 2,850lbs
    Determine the time to stop, assuming uniform deceleration
    Distance traveled during the deceleration
    Velocity of the vehicle after 3.2 sec's of braking

    2. Relevant equations

    V = (p2-p1)/time

    3. The attempt at a solution
    I currently do not have any attempts at a solution other than
    4200-2850 then divide that by 65?

    Hi ajayespinoza! :smile:

    Hint: Start by using good ol' Newton's second law to find the deceleration. :wink:
