Just before it is struck by a racket, a tennis ball weighing 0.560 N has a velocity of (20.0m/s)ı^−(4.0m/s)ȷ^(20.0m/s)ı^−( 4.0m/s)ȷ^. During the 3.00 ms that the racket and ball are in contact, the net force on the ball is constant and equal to −(380N)ı^+(110N)ȷ^−(380N)ı^+(110N)ȷ ^. What are the x- and y-components (a) of the impulse of the net force applied to the ball; (b) of the final velocity of the ball?

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) =_
