hat change would increase the acceleration of the dog sled? (1 point) Responses remove a dog from the sled remove a dog from the sled 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
Adding another dog to the sled would increase the acceleration of the dog sled.
To increase the acceleration of the dog sled, you can add another dog to the sled.
To determine which change would increase the acceleration of the dog sled, we need to consider Newton's second law of motion, which states that the acceleration of an object is directly related to the net force acting on it and inversely related to its mass.
1. Removing a dog from the sled: This change would decrease the mass of the sled, resulting in a decrease in inertia. According to Newton's second law, a decrease in mass would result in an increase in acceleration. So, removing a dog from the sled would increase the acceleration.
2. Adding another dog to the sled: This change would increase the mass of the sled. Again, according to Newton's second law, an increase in mass would result in a decrease in acceleration. So, adding another dog to the sled would not increase the acceleration.
3. Running the sled up a hill: This change would increase the force required to move the sled uphill. However, it would also increase the resistance caused by gravity, which opposes the motion. So, running the sled up a hill would not directly increase acceleration.
4. Adding more mass to the sled: As mentioned earlier, an increase in mass would result in a decrease in acceleration according to Newton's second law. Therefore, adding more mass to the sled would not increase the acceleration.
In conclusion, removing a dog from the sled would be the change that increases the acceleration of the dog sled.
