    8th one is a pretty simple one.

    The box's acceleration component along the incline is gsin(theta)
    theta is the angle of incline

    9
    here, the force of friction is (co efficient of friction) * (weight of the body)
    Accleration = netforce / mass
    guess yourself what net force would be!!
