Answer 2

The example that describes the given aspect in the question is option b:  A mother pushes a stroller up a ramp.

• In this case, machine work is only completed when an outside force is applied to a specific object, and its position is modified or reached a specific distance from its original position.
• Option a does not employ any form of simple machine and is simply a ball, hence it is not considered an example.
• Option b is a stroller, which is a simple contraption with wheels that are operated by the mother, changes positions, and goes a distance (by an external force).
• When counting money, there is no change in position in option c.
• Option d involves no machine or even a change in the distance when eating a sandwich.
• As a result, pushing a stroller is an excellent example of a basic machine at work.
