  1. how do u find the acceleration of the sled? and what applied force would be required to cause the sled to move at a constant velocity, explain your logic and show all your calculations.

  2. Fs = mg = 12kg * 9.8N/kg = 117.6N = Weight of sled.

    Fp = 117.6sin(o) = o. = Force parallel
    to plane due to sled.

    Fv = 117.6cos(o) = 117.6N. = Force
    perpendicular to plane due to sled.

    Ff = u*Fv = 0.42 * 117.6 = 49.4N =
    Force due to Kinetic friction.

    Fn = Fap - Ff = ma,
    82 - 49.4 = 12a,
    12a = 32.61,
    a = 2.72m/s^2.
