A spring stretches by 2.50 cm when a 3-kg object is suspended from its end. How much mass should be attached to this spring so that its frequency of vibration is 2.2 Hz? 3. A spring is compressed 18.0 cm using a force of 32 N. Find the amount the spring would compressed if a force of 10 N were used? 4. The diaphragm of a loudspeaker moves back and forth in simple harmonic motion to create sound. The frequency of the motion is 1.5 kHz and the amplitude is 0.20 mm. What is the maximum speed of the diaphragm? 5. A0.48-kg block is attached to the end of a horizontal spring and rest on a frictionless surface. The block is pulled so that the spring stretches for 0.32 cm relative to its unstrained length. When the block is released, its moves with the acceleration of 9.0 m/s'. What is the spring constant of the spring?. 6. A mass 5.00 kg is suspended from a spring and oscillates at 30 vibrations at 2 minutes. Find the spring constant. 7. A short spring with a spring constant of 850 N/m is compressed by 20 cm. How high above the starting point will a 250-g mass rise if fired vertically by this spring? 8. Find the frequency of a tuning fork that takes 3.75x10* s to complete one oscillation. 9. A 400-g mass at the end of a spring executes SHM with period of 3.2 s. Find the period of oscillation of a 800-g mass attached to the same spring? 10. When a 250-g mass is hung at the end of a vertical spring, the spring stretches 1.8 cm. How much further will it stretch if an additional 100-g mass is hung from it? D Focus
