A 85 kg runner taking part in a 200 m dash must run around the end of a track that has a circular arc with a radius of curvature of 32 meters. if he completes the 200 m dash in 23.9 s and runs at constant speed throughout the race, what is the magnitude of his centripetal force as he runs the curved portion of the track

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?
