Solve the following problems, and show all your work

Problem # 1 Explain how a vehicle's aerodynamic and styling requirements interact with each other.
Problem # 2 What is the viscosity force of a fluid with a coefficient of viscosity of 1.2x10-3 Ns/m2, between two boards moving at a relative velocity of 8 m/s, separated by 0.5 m, with a contact area of 3 m2?
Problem # 3 What is the Reynolds Number for an air flow of 25 m/s over an object with a length of 2 m? (Air density = 1.22 Kg/m3, and air viscosity = 1.8x10-5)
Problem # 4 What is the dynamic pressure of air in Problem 3?
Problem # 5 What are the aerodynamic impacts of a rear spoiler on a vehicle?
