Answer 2

Answer:

Given:

Force of 50N stretches an elastic wire.

The elastic potential energy stored is 40J.

To find:

Distance by which the wire was streched.

Concept:

Elastic Potential energy is a conservative form of energy. Since work was done to strech the wire, this work (energy) got stored in the wire as elastic Potential energy.

Formulas used:

Elastic Potential energy

= 1/2 × k × x².

Work = F × d

Calculation:

work = potential energy

=> F × d = 40

=> 50 × d = 40

=> d = 40/50 = 0.8 metres

So the answer is 0.8 metres.
