A ball is tossed with enough speed straight up so that it is in the air for several seconds. What is the velocity of the ball when it reaches its highest point? What is its velocity 1 second before it reaches its highest point? What is the change in velocity during this 1 second interval? What is its velocity1 second after it reaches it highest point? What is the change in velocity during the 1 second interval? What is the acceleration of the ball during any of these time intervals and at the moment the ball has zero velocity?

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) =_
