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.

sum= when you add is how much the whole amount is

distance= when you use angles and it means how far it goes

step-by-step explanation:

x/3-10=8

x/3=18

x=48
