What Force would be needed to extend a spring with a spring constant k=7 N/m that extends<br>0.3m?​
vladimir2022 [97]

Answer:

Force  =  - 2.1 Newton

Step-by-step explanation:

According to question ,

The value of Spring constant , K = 7  N/m   Newton per meter

And the spring is extended up to 0.3 meter

The Force experience on the spring is calculated from the Hook's Law

<u>The principal state that , the force applied on spring to extend or compress the spring to some distance is proportion to that distance. </u>

Let the force be F

So, F =  - K X

where K is spring constant and X is its displacement

Negative sign shows displacement of spring once it is stretched

And K is spring constant

So ,Force = ( - ) 7 × 0.3

I.e Force  =  - 2.1 Newton       Answer

They met 480 meters from the house.

<h3><u>Calculus</u></h3>

Given that Noah and his grandfather were returning home from a walk, and when they were 800 m away from the house, the grandfather said that he was thirsty, so Noah immediately ran home, got a bottle of water, and ran back to meet his grandfather who never stopped walking at a steady pace, to determine how many meters from the house did they meet if noah ran four times as fast as his grandfather walked, the following calculation must be made:

  • 200 x 4 = 800 - 200 = 600
  • 300 x 4 = 1200 - 800 - (800 - 300) = 100
  • 325 x 4 = 1300 - 800 - (800 - 325) = -25
  • 320 x 4 = 1280 - 800 - (800 - 320) = 480 - 480 = 0

Therefore, they met 480 meters from the house.
