(a) Estimate the terminal speed of a wooden sphere (density0.870 g/cm3) falling through air, if its radius is 8.00 cm and itsdrag coefficient is 0.500. (The density of air is 1.20kg/m3.)

Incorrect: Your answer is incorrect.

Your response is within 10% of the correct value. This may be dueto roundoff error, or you could have a mistake in your calculation.Carry out all intermediate results to at least four-digit accuracyto minimize roundoff error. m/s
