A shell is fired from a cannon with a velocity v(m/sec.) at an angle θ with the horizontal direction. At the highest point in its path it explodes into two pieces of equal mass. One of the pieces retraces its path to the cannon and the speed (in m/sec.) of the other piece immediately after the explosion is

An inductor having inductance L and a capacitor having capacitance C are connected in series. The current in the circuit increases linearly in time as described by I = Kt. The capacitor is initially uncharged. (To answer the following, use L, C, K, and t as necessary.) a) Determine the voltage across the inductor as a function of time. b)Determine the voltage across the capacitor as a function of time. c)Determine the time when the energy stored in the capacitor first exceeds that in the inductor.
