Answer:
The work performed by the girl is 150J.
Explanation:
The work done by a person is calculated if force applied and distance moved by an object is known. Work done is defined as the object is moved a distance when a force is applied on an object. Numerically Work done is multiplication of force applied and distance moved by an object
From given question we know that force applied is 15N (F) and distance moved by an object is 10m (S). To calculate work done substitute the given values in the formula
=
= 150J.
Thus we can say that work done by the girl is 150J.
