A 10.0 kg box is pulled along a horizontal surface by a 40N force which is applied at a 30.0 degree angle. If uk = 0.3, calculate the acceleration of the box.

    a = Fnet/M

    Fnet is the net force in the direction of motion

    Fnet = 40N*cos30 - M*g*uk

    a = (40/10)*cos30 -g*0.3
    = 3.464 - 2.940 = _____ m/s^2
