Plz help and answer as simple as possible thx! While building a fence, Adam drops a pile driver of mass 3000kg through a vertical distance of 8.0m. The pile driver is opposed by a resisting force of 5.0E6 N. How far is the stake driven into the ground on the first stroke?

If anyone who can me with this hw? i would really appreciate it

Which statement is true about an object that is moving in a circular motion due to centripetal force, f, when the radius of its circular motion is doubled? the new force then becomes equal to 2f the new force then becomes equal to f the new force then becomes equal to f/2 the new force then becomes equal to f2 the new force then becomes equal to 1/f

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?
