Some runners train with parachutes that trail behind them to provide a largedrag force. These parachutes are designed to have a large drag coefficient. Onemodel expands to a square 1.8mon a side, with a drag coefficient of 1.4. Arunner completes a 200mrun at 5.0m/swith his chute trailing behind. Howmuch thermal energy is added to the air by the drag force

In the circuit, the switch s has been open for a long time and r = 125 kohm. it is then suddenly closed. (a) determine the time constant before the switch is closed. s (b) determine the time constant after the switch is closed. _ s (c) let the switch be closed at t = 0. find the current in the switch as a function of time. (use t for time. express your answer in milliamps and seconds.) i(t) =_
