Reference no: EM13713496

Solve the following questions:

Question I: What is the drag force on a 1.6 m wide, 1.4 m high car traveling at 11 m/s (25 mph)? Suppose that the density of air is 1.2 kg/m³.

Question II: What is the drag force on a 1.6 m wide, 1.4 m high car traveling at 33 m/s (74 mph)? Suppose that the density of air is 1.2 kg/m³.

I am having a hard time understanding these questions. So if you answer please explain how you found the answers.
