Work is defined as the amount of force done multiplied by the distance it was applied. Since it is already given that the object of interest (a box of groceries) was lifted up 1 meter by a force of 5 newtons, work done can be solved using the following formula:
Work = Force * distance
Work = 5 N * 1 meter
Work = 5 N*m = 5 J
