A block of mass 0.469 kg is hung from a vertical spring and allowed to reach equilibrium at rest. As a result, the spring is stretched by 0.666 m. Find the spring constant. The block is then pulled down an additional 0.350 m and released from rest. Assuming no damping, what is its period of oscillation? How high above the point of release does the block reach as it oscillates? An undamped 1-76 kg horizontal spring oscillator has a spring constant of 33.1 me. While oscillating, it is found to have a speed of 2.54 mt's as it passes through its equilibrium position. What is its amplitude A of oscillation? What is the oscillator's total mechanical energy Em as it passes through a position that is 0.798 of the amplitude away from the equilibrium position? A 175 g object is attached to a spring that has a force constant of T15 me. The object is pulled 6.25 cm to the right of equilibrium and released from rest to slide on a horizontal, frictionless table. Find the locations of the object when its \eloeity.r is onethird of the maximum speed. Treat the equilibrium position as zero, Calculate the maximum spam Um of the object. positions to the right as positive. and positions to the left as negative. A point rotates about the origin in the xy plane at a constant radius of 0.225 m with an angular velocityr of 9.42 radfs. The projection of this point's motion on the x or yaxis is simple harmonic. What is the amplitude of the projected simple In What is the projected motion's frequency? E H: |:| s What is the projected motion's period
