Answer 2

Given:

John uses 50 N of force to push a shopping cart 10 meters.

To find:

Work done by John ? (in Joule unit)

Calculation:

Work is a form of energy expended by the operator to perform a job (in this case : pushing a shopping cart by a particular distance).

Mathematically , the work done by a force is given by the product of force with the displacement by which the object is moved.

$\sf{\therefore \: work = force \times displacement}$

$\sf{ = > \: work = 50 \times 10}$

$\sf{ = > \: work = 500 \: joule}$

So, work done by John is 500 Joule.

Hope It Helps.
