Finding the initial velocity of an object

  1. Apr 27, 2012 #1
    1. The problem statement, all variables and given/known data

    An object takes 12.3 meters to stop because of friction. Assume no skidding. If the coefficient of static friction is 0.86, what is the initial velocity of the object?

    2. Relevant equations

    initial velocity= mu*m*t

    3. The attempt at a solution

    welcome to pf!

    hi adorrea! welcome to pf! :smile:

    (have a mu: µ :wink:)

    use the work energy theorem

    work done = change in (mechanical) energy :smile:
