7) Imagine that you are standing stationary on a simple platform. Say for the sake of the problem that you have a mass of 50 kg. a) Draw the Force Diagram for this situation. What forces act on you as you are standing here? b) Now imagine that the platform accelerates upwards at a rate of 2 meters per second squared. What are the magnitudes of the forces that act on you now? 0) What would the magnitudes of the forces acting on you be if the platform instead accelerated at 2 meters per second squared downwards
