Homework Help: Work=Kinetic Energy formulas

  1. Feb 14, 2012 #1
    1. The problem statement, all variables and given/known data
    We have Work=Kinetic Energy which is :
    ##A=E_k=Fd=\frac{1}{2}mv^2##
    Find formulas of :
    Force, distance, mass, velocity squared and velocity


    2. Relevant equations
    ##A=E_k=Fd=\frac{1}{2}mv^2##


    3. The attempt at a solution
    ##F=\frac{\frac{1}{2}mv^2}{d}##

    ##d=\frac{\frac{1}{2}mv^2}{F}##

    ##m=\frac{2Fd}{v^2}##

    ##v^2=\frac{2Fd}{m}##

    ##v=\sqrt{\frac{2Fd}{m}}##

    Are all the formulas right found? Thanks ;)
