question 31

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 + 0.8 x - 1.02 $\times$ 10^-4 x² where y_o is the highest point, and x and y are the horizontal and vertical coordinates (in m) .

G_Moon = 1.62 m/s².

• A) 50 m/s
• B) 100 m/s
