For the following questions, decide whether work is being done or no work is being done. If work is being
done, calculate how many joules of work is being done and explain why work is being done. If no work is
being done, explain why no work is being done. Remember:
Work (Joules) = Force (Newtons) x Distance (Meters)

2. A weightlifter lifts a barbell from the ground to above her head 4 meters with 330 N of force.
3. A waiter carries a tray full of meals with a force of 10 N across the dining room which is 70 meters.
