SA5) Find the KE of a 500-g object after 1.0 meter of its fall from the top of a building. SA6) If the PE of the object in SA5 is twice as its KE, how high is it from the floor/ground? SA7) If the same object in SA5 and SA6 is to be placed back on top of the building where it was dropped, what will be its PE?
