A100 kg gymnast comes to a stop after tumbling. her feet do -5000j of net work to stop her. use the work-kinetic energy theorem to find the girl's initial velocity when she began to stop?
Answers: 2
(1)
the net work done on the gymnast
is the mass of the gymnast
is the final velocity of the gymnast, so her final kinetic energy is also zero:
is the initial velocity of the girl. By substituting the numbers and re-arranging the equation, we find:

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) =_
