A 1.40-g spider oscillates on its web, which has a damping constant of b = 3.50×10−5 kg/s . How long does it take for the spider's amplitude of oscillation to decrease by 18.0 % ? t = _____ s Last person didn't get it right, so using another question credit....
A 1.57-g spider oscillates on its web, which has a damping constant of b = 3.30×10−5 kg/s . How long does it take for the spider's amplitude of oscillation to decrease by 10.0 % ? I tried 210, 211, 219, and 220 and all those answers were wrong :C
Third times a charm.... I've posted this question twice and gotten them wrong twice. Hopefully someone can help me figure this one out. A 1.40-g spider oscillates on its web, which has a damping constant of b = 3.50×10−5 kg/s . How long does it take for the spider's amplitude of oscillation to decrease by 18.0 % ? The last two answers were 137.18 secs (which was wrong) and 6.88 secs (which was wrong as well).
A 9.10 kg object oscillates at the end of a vertical spring that has a spring constant of 2.25 times 10^4 N/m. The effect of air resistance is represented by the damping coefficient b = 3.00 N s/m. Calculate the frequency of the dampened oscillation. By what percentage does the amplitude of the oscillation decrease in each cycle? Find the time interval that elapses while the energy of the system drops to 3.00% of its initial value.
A 84.0 kg daredevil exhibitionist hangs on to the end of a long bungee cord attached to the railing of the Brooklyn Bridge and oscillates vertically. (Do NOT try this!) The spring constant of the bungee cord is 105 N/m, and the system's damping constant is 0.137 kg/s. How long does it take for the oscillation amplitude to decrease to 90.6 % of its initial value? time: s What is the frequency of oscillation? frequency: Hz
A 64.0 kg daredevil exhibitionist hangs on to the end of a long bungee cord attached to the railing of the Brooklyn Bridge and oscillates vertically. (Do NOT try this!) The spring constant of the bungee cord is 1.10×102 N/m, and the system's damping constant is 0.116 kg/s. How long does it take for the oscillation amplitude to decrease to 93.1 % of its initial value? time: s What is the frequency of oscillation? frequency: Hz
A car and its suspension system act as a block of mass m= on a vertical spring with k 1.2 x 10 N m, which is damped when moving in the vertical direction by a damping force Famp =-rý, where y is the 1200 kg sitting 4. (a) damping constant. If y is 90% of the critical value; what is the period of vertical oscillation of the car? () by what factor does the oscillation amplitude decrease within one period?...
As shown in the above diagram, a flat object of mass m = 11.8kg oscillates at the end of a vertical spring with a spring constant of k = 2060kg/s2. There is air resistance due to the shape of the object at the end of the spring where the damping coefficient is b = 3.05 kg/s. (a) What is the angular frequency of oscillation? (b) How long does it take for the energy of the system to decrease by 10%?
5. A pendulum has a period of 0.75 seconds and an undamped amplitude of 8.5. A damping force can be turned on which has a time constant of 4.5 s. A. What is the frequency of the oscillation without damping? B. Once the damping is turned on, how long will it take for the frequency to decrease to 35% of the undamped amplitude? C. How many oscillations will the pendulum make in the time determined in part B?
