For this case we have:
We have:
- Density of aluminum =
- Aluminum mass =
Clearing and substituting in the equation we have to:
Thus, the volume of the piece is
Answer:
The answer is A. 1,846,000.
Hope this helps! :)
<span>The characteristic equation for this is r^2 + yr + 1 = 0. Its roots are r = y/2 +/- isqrt(1-y^2/4). Finding the general solution to this equation gives us y = sqrt(20/9), which is the value of the damping coefficient y for which the quasi period of the damped motion is 50% greater.</span>
They run an equally amount of time because 10/4 = 2 and 1/2 and 5/2 = 2 and 1/2
