We have provided a body whose mass (m) is 100 kg and that body is moving with a Acceleration (a) of 2 m/s² and the distance (s) covered by that body is 50 m in the direction of applied force.
In the question we are asked to find the work done by the body. To calculate work done we have to use given below formula :
- Work done is a scalar quantity which is measured as the dot product of force (F) and displacement (s).
- SI unit of Work done is Joule (J)
- Dimension formula of Work done = [M¹L²T‾²]
But here we are not given the value of force. So, first we need find the force (F) by using Newton's second law :
Now, we have find the force (F). So, now we can calculate the work done by the body by applying the formula of work done :
