Answer:
180
180 because all three angles shows only because it is traingle
To solve this we are going to use the formula fro the force applied to a spring:

where

is the spring constant

is the extension
Since we know the

, we can replace that in our formula and solve for

:


where

is the acceleration

is the spring constant

is the extension

is the mass
We know for our problem that

,

, and

. So lets replace those values in our formula to find

:



We can conclude that the acceleration of the block when s=0.4m is

.
Sydney would arrive one hour before Nathan. 24/12=2 and 24/8=3
The multiplier for decreasing by 40% is 0.60. Since we want to know what was reduced by 40% (0.60), we divide the new price by the multiplier:
840 / 0.6 = 1,400
So the original price was 1,400
