What change would increase the acceleration of the dog sled? (1 point) Responses add another dog to the sled add another dog to the sled run the sled up a hill run the sled up a hill add more mass to the sled add more mass to the sled remove a dog from the sled
add another dog to the sled
To increase the acceleration of a dog sled, you would want to reduce the mass of the sled. Therefore, the correct answer is "remove a dog from the sled."
To determine which change would increase the acceleration of the dog sled, we can consider Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
1. Adding another dog to the sled: Adding another dog would increase the net force on the sled since there is now an additional force contributing to the pulling. This would likely increase the acceleration of the sled.
2. Running the sled up a hill: Running the sled up a hill would also increase the net force on the sled since the dogs would now have to overcome the force of gravity in addition to any other resistance. This would likely increase the acceleration of the sled.
3. Adding more mass to the sled: Adding more mass to the sled would increase its overall mass. According to Newton's second law, an increase in mass would result in a decrease in acceleration for the same net force. Therefore, adding more mass to the sled would not increase its acceleration.
4. Removing a dog from the sled: Removing a dog from the sled would reduce the net force acting on the sled since there would be one less force pulling it. As a result, the acceleration of the sled would likely decrease.
Based on this analysis, the changes that would most likely increase the acceleration of the dog sled are adding another dog to the sled and running the sled up a hill.
