Question 17
Original source text (the original panel preserves all diagram labels, tables and choices):
Refer to the figure below:
If friction and wind resistance are ignored, a bobsled run illustrates how kinetic
energy and potential energy can be interconverted, while the total mechanical
energy remains constant. What are the values for W and X?
A. W = 200,000 J; X = 200,000 J C. W = 250,000 J; X = 200,000 J
B. W = 200,000 J; X = 400,000 J D. W = 250,000 J; X = 400,000 J
