SERPSE10 15.5.OP.025. 5. [-/6.66 Points] DETAILS MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A meter stick is attached to one end of a rigid rod with negligible mass of length /= 0.322 m. The other end of the light rod is suspended from a pivot point, as shown in the figure below. The entire system is pulled to a small angle and released from rest. It then begins to oscillate. (a) What is the period of oscillation of the system (in s)? (Round your answer to at least three decimal places.) (b) By what percentage does the period of the system found in part (a) differ from the period of a simple pendulum 0.822 m long? IT simple-system! 100% = % simple Need Help? Read It Submit Answer 6. [-16.66 Points] DETAILS SERPSE10 15.6.OP.028. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A metal block with a mass of 4.00 kg oscillates at the end of a vertical spring with a spring constant of 2.40 x 10 N/m. The motion is damped by air resistance, and the damping coefficient is b = 3.00 N. s/m. (a) What is the frequency (in Hz) of the damped oscillation? Hz (b) By what percentage does the amplitude of the oscillation decrease in each cycle? (c) Over what time interval (in s) does the energy of the system drop to 3.00% of its initial value? (d) What If? The atmosphere of Venus is 50 times thicker than that on Earth. If the effect of air resistance on Venus is represented by b = 150 N s/m, recalculate the answers for parts (a) to (c) for this system if it is set in motion in the atmosphere of Venus. What is the frequency (in Hz) of the damped oscillations? Hz What is the percentage decrease in amplitude in each cycle? What is the time interval (in s) for the energy to drop to 3.00% of its initial value? Need Help? Read it Submit Answer
