Question

work done by a frictional force f on a rolling ball which completes d distance before stopping is​

Answer 1

Answer:

As we know that the work done is the product of force vector and displacement vector. We can also take work done

W = - du/dt which is negative of potential energy per time

Explanation:

W = F × S

Answer 2

work=force*displacement
In this case the force is in the opposite direction of displacement
So, work=-fd
