Askiy diver, with parachute unopened, falls 625 m in 15.0s.
then she opens her parachute and falls another 356 m in142 s. what
is her average velocity (both magnitude anddirection) for the
entire fall?

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 3.00 ms . you then use the resistor and capacitor to make a low-pass filter. what is the crossover frequency fc?
