Show your work: A wolf is chasing an elk. The wolf has a mass of 100 kg and is running with a velocity of 16 m/s to the right. What is the wolf’s momentum? The elk has a mass of 180 kg. What does the elk’s speed have to be for it to have the same momentum as the wolf?

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?
