n undamped 1.47-kg horizontal spring oscillator has a spring constant of 25.1 N/m. While oscillating, it is found to have a speed of 3.17 m/s as it passes through its equilibrium position. What is its amplitude of oscillation? What is the oscillator\'s total mechanical energy as it passes through a position that is 0.651 of the amplitude away from the equilibrium position?
A string vibrates in five segments to a frequency of 460Hz. (a) what is its fundamental frequency? (b) What frequency will cause it to vibrate in three segments.
