The gravitational potential energy (PE) of the stuntwoman can be calculated using the formula:
PE = mgh
where m is the mass (in kg), g is the acceleration due to gravity (in m/s^2), and h is the height (in m).
Thus, substituting the given values:
PE = (40.0 kg)(9.8 m/s^2)(40.0 m)
PE = 15,680 J
Therefore, the answer is C. 15,680 J.
