A 0.58-kg mass is hanging from a spring with spring constant 20 N/m. Then the mass is displaced from the equilibrium by 2.9 cm and let go. What is the resulting angular frequency of the oscillation?(use rad/s as units)
A 276g ball is tied to a string. It is pulled to an angle of 5.00 degrees and released to swing as a pendulum. How long is the string
A purple beam is hinged to a wall to hold up a blue sign. The beam has a mass of mb = 6.9 kg and the sign has a mass of ms = 15.4 kg. The length of the beam is L = 2.57 m. The sign is attached at the very end of the beam, but the horizontal wire h..
