A physics student observes a ball as it roll's down a ramp. She collects the following data.
mass = 38 grams
acceleration = 2 m/s2
initial velocity = 0 m/s
final velocity =l6 m/s
radius = 4 cm
How long did it take to roll down the ramp?

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?
