Multiple Choice

Use the following scenario to answer the next problem.
NASA's "Weightless Wonder" flights can simulate "zero-g" or some other extraterrestrial gravity by flying a C-9 jet plane in a parabolic path.One path the plane takes is expressed as y = y_o + 0.8x – 1.02 x10^-4 x² where y_o is the highest point, and x and y are the horizontal and vertical coordinates (in m) .
-What is the horizontal speed of the plane if the flight is to simulate lunar gravity, g_Moon = 1.62 m/s².

A) 50 m/s
B) 100 m/s
C) 150 m/s
D) 200 m/s
E) 250 m/s
