A 51 g ball of clay traveling at speed 6.6 m/s hits and sticks to a 1.0 kg block sitting at rest on a frictionless surface. What is the speed of the block after the collision?

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?
