    Answer:0.3

    Explanation:

    Coefficient of kinetic friction = frictional force / Normal reaction

    normal reaction = mgcosA

    m = mass=28.6kg

    g = 9.8m/s and A is angle 24°

    Normy reaction = 28.6*9.8cos24=256N

    Frictional force = 77.3N

    Coefficient of kinetic friction = 77.3/256=0.3
