A199 g oscillator in a vacuum chamber has a frequency of 1.58 hz . when air is admitted, the oscillation decreases to 44.2 % of its initial amplitude in 46.5 s . what is the dampening constant of the oscillation? the answer needs to be in the unit - seconds.

Visualize the problem and identify special cases first examine the problem by drawing a picture and visualizing the motion. apply newton's 2nd law, ∑f⃗ =ma⃗ , to each body in your mind. don't worry about which quantities are given. think about the forces on each body: how are these consistent with the direction of the acceleration for that body? can you think of any special cases that you can solve quickly now and use to test your understanding later? one special case in this problem is if m2=0, in which case block 1 would simply fall freely under the acceleration of gravity: a⃗ 1=−gj^.
