Question

what would increase the acceleration of a dog sled.

A.add another dog.
B.remove a dog
C.add more mass to the sled
D.run the sled up a hill

Answer 1

A and C would increase the acceleration of a dog sled.

Adding another dog would increase the pulling force and therefore increase the acceleration.

Adding more mass to the sled would increase the force required to pull it, but assuming the same number of dogs, it would also increase the overall force exerted on the sled, leading to increased acceleration.

Removing a dog or running the sled up a hill would decrease the acceleration since there would be less pulling force available to move the sled.

Answer 2

[AI-generated answer — Step-by-Step Bot]

To increase the acceleration of a dog sled, you can take the following steps:

1. Option A: Add another dog - Adding another dog to the sled will increase the pulling force, which can result in greater acceleration.

2. Option C: Add more mass to the sled - By increasing the mass of the sled, you can improve traction and increase the overall force applied to propel the sled forward.

3. Option D: Run the sled up a hill - Moving the sled up a hill requires the dogs to generate more force to overcome gravity. This will result in an increased acceleration when they start moving downhill.

Therefore, the correct options to increase the acceleration of a dog sled are A (add another dog), C (add more mass to the sled), and D (run the sled up a hill).

Answer 3

[AI-generated answer — Explain Bot]

To determine which option would increase the acceleration of a dog sled, let's analyze each choice:

A. Add another dog: Adding another dog to the sled would increase the total force generated by the dogs, resulting in increased acceleration. The more dogs providing propulsion, the greater the force exerted.

B. Remove a dog: Removing a dog from the sled would decrease the total force generated by the dogs, resulting in decreased acceleration. With fewer dogs providing propulsion, the force exerted on the sled would be reduced.

C. Add more mass to the sled: Adding more mass to the sled would increase the inertia of the system, making it harder to accelerate. Increasing the mass without increasing the propulsive force would result in decreased acceleration.

D. Run the sled up a hill: Running the sled up a hill would increase the incline of the surface, causing gravitational potential energy to convert into kinetic energy and contribute to the sled's acceleration. The gravitational force acting on the sled in the downhill direction would provide an additional force in favor of acceleration.

Therefore, option A (add another dog) and option D (run the sled up a hill) would both increase the acceleration of the dog sled.
