Compare the collision between two baseballs and a catcher's mitt. Case A: A baseball pitched at 40 m/s collides with a catcher's mitt and is brought to a stop. The catcher holds the mitt rather rigidly and retracts backwards very little as the ball strikes the mitt. Case B: An identical baseball pitched at 40 m/s collides with a catcher's mitt and is brought to a stop. The catcher holds the mitt with a relaxed arm and reracts backwards 30 cm as the ball strikes the mitt.
Which variable is different for these two cases?
Which case involves the greatest momentum change? … the greatest impulse? … the greatest force?

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?
