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) .
-Suppose y_o = 10000 m and the lowest height is 2000 m,how long is the flight with a simulated lunar gravity g_Moon = 1.62 m/s²?

A) 44 s
B) 100 s
C) 40 s
D) 60 s
E) 66 s
