A force due to gravity on a body is 1800N. This body has to be lifted to the height 50cm using a slope. The maximal force which can be used to lift the body is 600N. Neglect the friction and find the minimal length of the slope required to accomplish this task.Hint: The force due to gravity can be decomposed into two directions. The normal force F1 is compensated by the reaction of the slope. The force F2 parallel to the slope is required to overcome if we wish to lift the body (see the picture).
