Object A has a momentum of 24kgm/s and hits Object B, which already has a momentum of 15kgm/s. After the collision Object B now has a momentum of 31kgm/s. What must the final momentum of the Object A be?

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?
