The amplitude of a lightly damped oscillator decreases by during each cycle. What percentage of the mechanical energy of the oscillator is lost in each cycle?
If a car has a suspension system with a force constant of N/m, how much energy must the car’s shocks remove to dampen an oscillation starting with a maximum displacement of 0.0750 m?
A car with a mass of kg bounces vertically with an initial velocity of 0.940 m/s, returning to its original vertical position after bouncing. How much energy must the car’s shock absorbers dissipate in order to dampen the bounce? Assume that the drag is negligible.
