ohh sorry, in my first question...

A 15 kg box sits on a horizontal FORCE.

the coefficient of static fricition between the box and the surface is 0.70. if a force P is exerted on the box at an angle directed 37 degrees below the horizontal, what must be the magnitude of P to get the box moving??

``IT SHOULD BE A 15 kg box sits on a horizontal SURFACE and not A 15 kg box sits on a horizontal FORCE....

    We did this problem for you below. I have a typo
    force down is 15*9.8 not 15
    WLS did it all out for you.

  • Physics -

    force down = 15 * 9.8 + P sin 37
    force horizontal = P cos 37
    0.7 (15 * 9.8 + P sin 37) = P cos 37

    We both assumed that you meant horizontal surface.

    ok...thanks a lot.....
