Amy pulls a spring with a spring constant k = 100 stretching it from its rest length of 0.10 m to 0.2

Elastic potential energy  E = 0.5 J

Explanation:

Let us assume we have to find the elastic potential energy stored in the spring.

Given: k = 100

change in the length of the spring x = 0.2-0.1 = 0.1 m

Elastic potential energy

E =

plugging the values we get

Hence, Elastic potential energy  E = 0.5 J

you cant move and you feel like someones pushing you down onto your bed it can feel like you want to get up but you just can't it can be extremely scary
