1 Find the acceleration of an object if there is a force of 20 newtons in one direction and 10 newtons in the opposite direction. The mass if 2 kg.

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?
