Deceleration rate

  1. Jun 9, 2008 #1
    I apologize for my ignorance, I'm an extreme newbie in physics.
    Is it possible to determine the deceleration rate of a car only with following information?

    initial velocity = 60mph (96km/h)
    final velocity = 0mph (0km/h)
    distance = 146ft (44.5m)

    if so, how many distance would it take to stop from 60km/h (37.5mph)?

    Thank you

    v=Final velocity
    u=initial velocity

    do a search for newton's laws of motion. they are probably the most well known equations for scientists and engineers and worth remembering. there are a few other derivations than the one that rock freak has given you.
