during a circus performance, a 64 kg human cannonball is shot out of a 22 m long cannon, if the himan cannonball spends 1.1 s in the cannon, determine the average net force on him in the barrek if the cannon

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) =_
