A 2.00 kg cart (cart#1) moving to the right at 12.0m/s collides with a 1.20 kg cart (cart#2) moving to the right at 2.00m/s. The two carts stick together and move to the right after the collision. A. What is the initial momentum of cart#1? B. What is the initial momentum of cart#2? C. What is the total momentum of both carts after the collision? D. What is the final velocity of both carts after the collision? E. What is the final momentum of cart#1? F. What is the final momentum of cart#2? G. If the total time for the collision was 0.015s, what was the average impulsive force exerted by cart#1 on cart#2? H. What was the average impulsive force exerted by cart#2 on cart#1? I. Was total momentum conserved in this collision? Was total mechanical energy conserved in this collision? Explain.

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) =_
