1a)A block of mass=100kg is tied to a donkey that moves with constant acceleration of 20cm/s^2 up a 30 degree incline. What is the force with which the donkey pulls on the block parallel to the incline? the coefficient of kinetic friction between the incline and the block is 0.30.

1b) how large is the force with which the block pulls on the donkey?

1c) how large is the normal force?

1d) what is the force that the donkey of mass M,applies on the incline?

1e) if the rope that ties the box to the donkey is cut, what will the acceleration of the box be?
