question 15

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

Definitions:

Probability

A measure of the likelihood of a particular event's occurrence, ranging from 0 (impossible) to 1 (certain).

P < 0.05

Indicates that the probability of the observed data, or more extreme, occurring by chance is less than 5%, commonly used to determine statistical significance in hypothesis testing.

Population Standard Deviation

The square root of the variance in the full population, indicating how much each member of this population deviates from the population mean.

Sample Standard Deviation

A measure of the amount of variation or dispersion of a set of values in a sample from its mean.
