Athread holds two carts together on a frictionless surface. a spring is compressed
between the two carts. after the thread between the two carts is cut the cart on the
left with a mass of 1.5 kg moves away with a velocity of 27 cm/s. what is the
velocity of the cart on the right that has a mass of 4.5 kg? thisss is the answer i just need to show work> > > > > > > (0.09 m/s)

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) =_
