A 25 kg box is along a horizontal floor and a force of 400 N pushes the box with an angle of 50 deg with the horizontal. Starting from rest, the box achieves a velocity of 2 m/s in a time of 4 seconds. Find the coefficient of sliding friction between box and the floor.

  1. break the pushing force into vertical and horizonal components, Fv, Fh


    Now, write the force equation
    fh-mu*(mg+Fv)=ma solve for mu, knowing acceleration is frdom
    a=changevelocity/time=2/4 m/s^2=.5m/s^2
