    Vf^2=vi^2+2ad solve for d

  • physics - ,

    but qhats thhe Vf in the problem

  • physics - ,

    Vf= final velocity
    Vi= initial velocity

  • physics - ,

    i knoww but how do u find out what tge final velocity is in this problem

  • physics - ,

    What does "to rest" mean? What velocity is "at rest"?
