Assuming that the diver's drag coefficient C does not change from one position to the other, find the ratio of the effective cross-sectional area A in the slower position to that in the faster position. 010 016 Units the tolerance is +/-2% 034 Click if you would like to Show Work for this question: 039 Question Attempts: 0 of 5 used SAVE FOR LATER SUBMIT ANSWER 042 044 048 057 Review Results by Study objective

Explanation / Answer

V = sqroot ( 2W/cp A)

176 km/hr= 48.89 m/s

338 km/hr= 93.89 m/s

48.89 = sqroot ( 2W/cp A1)

93.89= sqroot ( 2W/cp A2)

(48.89 / 93.89)^2 = A2/A1

A2/A1= 0.2711 apprx
