The correct answer would be to add another dog to the sled. Increasing the number of dogs pulling the sled would result in increased force and thus increased acceleration.
To increase the acceleration of a dog sled, you can add another dog to the sled.
To increase the acceleration of the dog sled, the correct answer is to add another dog to the sled. This is because the force generated by the dogs pushing against the ground contributes to the acceleration of the sled. By adding another dog, you increase the total force exerted on the sled, resulting in a greater acceleration.
