Quizplus · Accepted Answer

When carrying the bag of groceries at a constant velocity, there is no net force acting on the bag in the vertical direction (assuming the bag is not accelerating or slowing down). Therefore, the work done on the bag is zero. We can use the following formula to calculate work done:

Work = Force x Distance x cos(theta)

Since there is no net force acting on the bag, the work done is zero. Therefore, the best choice is A) 0.0 J.
