achieve

(7%) Problem 9: Calculate the velocity a spherical rain drop would achieve falling (taking downward as positive) from 52 km in the following situations. Randomized Variables h-5.2 km d- 1.25 kg/n3 50% Part (a) Calculate the velocity in the absence of air drag in m/s. 50% Part (b) Calculate the velocity with air drag in m/s. Take the size across of the drop to be 3.2 mm, the density of air to be 1.25 kg/m, the density of water to be 1000 kg/m, the surface area to be Tr2, and the drag coefficient to be 1.0 Grade Summary 0% 100% Potential sino cotan() atan coshO tanO acoso acotan) si0 cos asin) Attempts remaining: IS (2% per attempt} detailed view 4 5 6 tanh cotanh0 ODegrees Radians Submit Hint l give up!
