Ball a is dropped from the top of a building of height h at the same instant that ball b is thrown vertically upward from the ground. when the balls collide, they are moving n opposite directions, and the speed of a is twice the speed of b. at what height does the collision occur? (use any variable or symbol stated above as necessary.) both balls experience constant acceleration once they are �n flight. choose a coordinate system with the origin at the ground and the upward direction positive. when the balls collide they are at the same height above the ground.

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?
