A 61.0 kg bungee jumper, tied to a 37.0 m long cord, leaps off a bridge whose deck is 67.0 m above the water. He falls to 8.0 m above the water before the bungee cord pulls him back up. What is the magnitude of the impulse exerted on the bungee jumper while the cord stretches?
A 5.9 H coil with a resistance of 84.960 Ohm is in series with a 373.824 Ohm resistor. This circuit is connected to an AC voltage source that gives 158 V (rms) at 36 Hz. What is the rms value of the potential difference across the resistor?
