An object is attached to a vertical spring and slowly lowered to its equilibrium position. this stretches the spring by an amount d. if the same object is attached to the same vertical spring but permitted to fall instead, through what maximum distance does it stretch the spring?

h=2d

Explanation:

As is known, in equilibrium position,

The position maximum spring stretch after the mass is dropped so:

Since (d+y)>0

K=m*g with out friction

h=(d+y) so :

The maximum distance is h=2d

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

from the given table,

for females, the age of a male 3 years younger should be used.

so, we have to check for 24 year male for 20 year endowment.

it is 42.34 for every $1000 face value.

for a face value of $25000,

it is 25 * 42.34 = $1058.50

∴ emily ruth's annual premium is $1058.50
