Question

What is the drag force? Part What is the drag force on a 1.6 m wide, 1.4 m high car traveling at 14 m/s ( 31 mph)? Suppose that the density of air is 1.2 kg/m3 Express your answer to two significant figures and include the appropriate units. D=5.67 IN Submit Give U Incorrect; Try Again; 4 attempts remaining Part B What is the drag force on a 1.6 m wide, 1.4 m high car traveling at 42 m/s (94 mph)? Suppose that the density of air is 1.2 kg/m3 Express your answer to two significant figures and include the appropriate units.

Explanation / Answer

Drag force= (1/4)(density of air)(Area)(v^2)

D= (1/4)(1.2kg/m^3)(1.4mx1.6m)(42 m/s)^2
D= 1185.4 N
