    Friction
    A 200-N sled is pushed along a horizontal surface at constant speed with a 50-N force that makes an angle of 28 degrees below the horizontal. What is the coefficient of kinetic fricition?

    component of 50 N along direction of motion = 50cos28= 44.14 N
    coefficient of friction = 44.14/200 = 0.2207
