Final answer:
The jug of milk and soda can are likely easiest for a sanitation worker to carry alone to the truck due to their manageable sizes and shapes, despite each object ostensibly weighing 40 pounds.
Step-by-step explanation:
To determine which object would be easiest for one sanitation worker alone to carry to the collection truck, if each item weighs approximately 40 pounds, we should consider factors like size, shape, and the ease of gripping the object. Given the list that includes a dog, camper, soda can, two elephants, television set, baby bottle, jug of milk, and an automobile, it's clear that many of these items are either too bulky or impossible to carry by a single person, regardless of their hypothetical 40-pound weight. The jug of milk and soda can are most likely the easiest to carry due to their manageable sizes and convenient shapes for holding, with the jug of milk being the most practical given it's designed to be carried by one person.
Assuming each object weighs approximately 40 pounds, the soda can is the lightest and easiest to carry. A soda can typically weighs around 0.5 pounds, which is significantly lighter compared to the other objects mentioned.
When considering the weight a sanitation worker can handle, it would be more feasible for them to carry a soda can rather than a dog, camper, elephants, television set, baby bottle, jug of milk, or an automobile.
