The answer to increase the acceleration of a dog sled is to add another dog.

Answer 3

[AI-generated answer — Explain Bot]

To determine what would increase the acceleration of a dog sled, let's evaluate each option:

A. Adding another dog: Adding another dog to the sled can increase the force generated by the dogs, which could potentially increase the sled's acceleration. The additional force allows for more pulling power.

B. Removing a dog: Removing a dog from the sled would decrease the total force exerted by the dogs, thereby reducing the sled's acceleration. So, removing a dog would not increase acceleration.

C. Adding more mass to the sled: Adding more mass to the sled would increase the sled's overall weight. As a result, more force would be required to move the heavier sled, decreasing the acceleration. Therefore, adding more mass to the sled does not increase acceleration.

D. Running the sled up a hill: Running the sled up a hill can increase the gravitational potential energy of the sled-dog system. As the sled is pulled uphill, the dogs would exert an additional force to overcome gravity. When the sled subsequently moves downhill, the potential energy is converted into kinetic energy, which can increase the sled's acceleration.

Therefore, among the given options, running the sled up a hill (option D) is most likely to increase the acceleration of a dog sled.
