An RLC circuit is connected to a AC power supply. The amplitude of the power supply is 180.0V. To determine the maximum voltage across any element of the circuit one must determine the frequency at which it occurs. For the resistor, it is the resonance frequency. But what about the inductor or capacitor? Determine the maximum amplitude of the voltage across the inductor if R=90.0 ohms, C=5.4F, and L=25.0mH.

A23 kg log of wood begins from rest, 300 m up a sluice (a water track used to transport logs, think of it as an inclined plane with negligible friction) inclined at 20° to the horizontal. after it reaches the flat waterway at the bottom it collides elastically with a 100 kg block of wood initially at rest near the base of the incline. (a) how long does it take the 23 kg log to travel down the incline? (b) what is the speed of the 23 kg log at the bottom of the incline? (c) what are the velocities of both blocks of wood after the collision? (d) what is the total kinetic energy before the collision? (e) what is the kinetic energy of the 23 kg log after the collision? (f) what is the kinetic energy of the 100 kg block of wood after the collision? (g) what is the total kinetic energy after the collision? (h) compare the total initial and total final kinetic energies. is this consistent with what you would expect for elastic collisions? explain!
