I commute from Sparkle town to my High School each weekday. In this commute, I first travel at 18 m/s for 60 seconds. I then stop at a light for 60 seconds. Last, I travel at 12 m/s for 120 seconds. How much distance (in total) did I travel in my morning commute?

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?
