a blockof mass 100 kg tied to a donkey that moves with constant accelaration of 20centimeter over second squared up a 30 degrees incline. what is the force with which the donkey pulls on the block parallel to the incline? The coefficient of kinetic friction between the kinetic friction between the incline and the box is 0.30.
