Two gliders are on a frictionless, level air track. both gliders are free to move. initially, glider a moves to the right and glider b is at rest. after the collision, glider a has reversed direction and moves to the left. the mass of glider a is one quarter of the mass of glider b. the system is defined as the two gliders. which object has the higher change in momentum?

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) =_
