In the figure, a very small toy race car of mass 60 g is released from rest on the loop-the-loop track. If it is released at a height shown (above the floor) for R = 1.3 m, how high, in m, is it above the floor when it leaves the track, neglecting friction? Provide your answer with two decimal places. When rounding, in case of a 5, round it up 2R R
