A vehicle moving horizontally gets a load of wind resistance acting in the opposite direction to the
vehicle's motion
F
M
cv?
v is the horizontal speed of the vehicle.
F is the thrust that comes from the vehicle engine
c damping coefficient for wind resistance force (c =0.20 N.sec2/m2)
M is the mass of the vehicle (M = 1000 kg)
Using Newton's 2nd law, we get the equation of motion
dv
1000-
+ 0,2 v² = F
dt
At steady state the speed of the car is vo = 30 m/s and thrust F, = 0.2 v3 = 180 N. If the car is moving
at a speed around steady state v = vo + dv = 180 and F = F, + 8F, derive a linear differential
equation connecting d(dv)
,8v and SF.
