A: An airplane has an effective wing surface area of 18 m2 that is generating the lift force. In level flight the air speed over the top of the wings is 61.5 m/s, while the air speed beneath the wings is 58.5m/s. What is the weight of the plane?

B: An antifreeze solution is made by mixing ethylene glycol (ρ = 1112 kg/m3) with water. Suppose that the specific gravity of such a solution is 1.1100. Assuming that the total volume of the solution is the sum of its parts, determine the volume percentage of ethylene glycol in the solution.
