Two Formula 1 race car drivers are taking off from the start line at the Russian Grand Prix. Both accelerate from rest at about 14.9 m/s2, but the second driver's car hits its max speed 8.9 seconds before the first and stops accelerating. How many meters farther did the first driver travel than the second driver in that time?

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) =_
