A 70 kg person does a bungee jump from a bridge and falls straight down. The natural length of the bungee cord is 20 m and it has a spring constant k of 80 N/m. When the bungee cord has a total length of 25 m, what is the sign and magnitude of the y-component of acceleration of the jumper in units of m/s2

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?
