Two different simple harmonic oscillators have the same natural frequency (f=9.10 Hz) when they are on the surface of the Earth. The first oscillator is a pendulum, the second is a vertical spring and mass. If both systems are moved to the surface of the moon (g=1.67 m/s2),
what is the new frequency of the pendulum?
Calculate the new frequency of the vertical spring and mass.
The nucleus of a helium atom contains two protons. In a simple model of this nucleus, What is the electric potential energy of the two protons
A uniform disk of mass 4m is rotating an a plane parallel to the ground with angular frequency of 12 rad/sec. What fraction of kinetic energy was lost
Skier loses a ski at the top of a 98 m hill. The ski proceeds to glide down the hill frictionless. Illustrate what speed is the ski traveling at the bottom of the hill?
A spring with 49 N/m hangs vertically next to a ruler. The end of the spring is next to the 17-{rm cm} mark on the ruler. If a 2.0-{rm kg} mass is now attached to the end of spring, where will the end of the spring line up with the ruler marks.
