А. The amplitude of a linearly damped harmonic oscillator decreases from 60.0 cm to 40.0 cm in 10.0 s. What will be the amplitude of the harmonic oscillator after another 10.0 s passes? A. 20.0cm D. 0.00 cm E. 26.7 cm C. 30.0 cm ith o forca constant of 50 N/m. An oscillating force B. 16.7 cm

less than one you can't create energy

the answer is b, have negligible mass

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
