A high-speed car with m = 2000 kg, CD = 0.3, and A = 1 m2 deploys a 2-m parachute to slow down from an initial velocity of 100 m/s (Fig.) Assuming constant CD, brakes free, and no rolling resistance, calculate the distance and velocity of the car after 1, 10, 100, and 1000 s. For air assume ρ = 1.2 kg/m3, and neglect interference between the wake of the car and the parachute.
