    Normally the push force given to me in N but for some odd reason, it's given in velocity(m/sec). How do i change that m/s into N?!?!?

    They gave you a CHANGE in velocity (from rest to 1.6 m/s) and a time. Use that to find the acceleration and then it's straight Newton's 2nd

    0.72*0.8 is the right side of the equation

    \(F_{applied} - F_f\) is the left side

    You're solving for \(F_{applied}\)
