Ametal block with a mass of 7.20 kg oscillates at the end of a vertical spring with a spring constant of 2.00 ✕ 104 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? 8.3881 hz correct: your answer is correct. (b) by what percentage does the amplitude of the oscillation decrease in each cycle? 2.4531 correct: your answer is correct. % (c) over what time interval (in s) does the energy of the system drop to 5.00% of its initial value? 0.246 s incorrect: your answer is incorrect. enter a number. (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? what is the percentage decrease in amplitude in each cycle? % what is the time interval (in s) for the energy to drop to 5.00% of its initial value?
