Stretched 1 m beyond its natural length, a certain spring exerts a restoring force of magnitude 50 newtons. how much work, w, does it take to stretch the spring 7 m beyond its natural length?

1,225 J

Step-by-step explanation:

The restoring force exerted by a spring is given by:

Where 'k' is the spring constant and 'x' is the stretched distance.

Since x=1, the spring constant is:

The work required to stretch a spring is given by:

The work needed to stretch this spring 7 m beyond its natural length is:

The work required is 1,225 J.

hey seth! : )

i’m not 100% sure, but i think it’s b

hope this ya : p

miss u!
