What change would increase acceleration of a dog sled add another down to the sled remove a dog from the sled, rent a slide up a hill, or add more mass to the sled
Adding more mass to the sled would increase the acceleration of a dog sled.
To increase the acceleration of a dog sled, adding more mass to the sled would be the most effective change. This is because increasing the mass of the sled will increase the force required to move it, resulting in a greater acceleration. Adding another dog to the sled might also increase acceleration to some extent since it will add more pulling force, but adding mass would have a greater impact. On the other hand, removing a dog from the sled would decrease the available pulling force and likely decrease acceleration. Renting a slide up a hill would not directly affect the acceleration of the dog sled.
To increase the acceleration of a dog sled, there are a few factors to consider. Let's go through each option you mentioned and explain how it would affect the acceleration:
1. Add another dog to the sled: This option would likely increase the acceleration of the sled. More dogs pulling the sled would generate more force, leading to greater acceleration.
2. Remove a dog from the sled: Removing a dog from the sled would decrease the total force used to pull the sled and thus decrease the acceleration. Therefore, this option would not increase the acceleration but rather decrease it.
3. Rent a slide up a hill: Renting a slide and going up a hill would not directly affect the acceleration of the sled. While going uphill requires more force, the acceleration is determined by the push and pull forces acting horizontally on the sled. Therefore, this option would not necessarily increase the sled's acceleration.
4. Add more mass to the sled: Adding more mass to the sled would increase its inertia, which is the resistance of an object to changes in motion. This increased inertia would make it more difficult for the dogs to accelerate the sled, therefore decreasing its acceleration. So, this option would not increase the acceleration of the sled but rather decrease it.
In conclusion, the option that would increase the acceleration of a dog sled is to add another dog to the sled. Adding more force (in this case, another dog) would increase the sled's acceleration.
