What is the drag force on a 1.6 m wide, 1.4 high car traveling at
A) 10 m/s B) 30 m/s
I'm getting 68 N for part a and 615 N for part B using equation D=.25pAv^2
P= density of air (1.22 kg/m^3) and A is cross sectional area of obect as it faces the wind). *I plugged in 1.22 for p, 2.24 for A, and 30 for v but this is wrong according to the book. What am I doing wrong?
And I don't think I need it to solve this problem but *v terminal = sq rt (4mg/pA).
