The acceleration of the dragster is modeled as a D c1 c2v2, where the v2-term accounts for aerodynamic drag and where c1 and c2 are positive constants. If, from wind tunnel tests, c2 is known, determine the value of c1 so that the final speed is vf , assuming it starts from rest and travels a distance d to the finish. A

You have a resistor and a capacitor of unknown values. first, you charge the capacitor and discharge it through the resistor. by monitoring the capacitor voltage on an oscilloscope, you see that the voltage decays to half its initial value in 2.70 miss . you then use the resistor and capacitor to make a low-pass filter. what is the crossover frequency fc?
