Question

A sled is moving down a steep hill. The mass of the sled is 50 kg and the net force acting on it is 20 N. What must be done to find the acceleration of the sled? Which ones apply to this scenario.
1. The force of gravity must be broken into its parallel and perpendicular components.

2. Acceleration can be found by dividing the net force by mass.

3. Acceleration can be found by multiplying the net force by mass.

4. The magnitude of the force components must be multiplied by gravity.

5. Trigonometry can be used to solve for the magnitude of the force components.

6. Net force must be found before acceleration can be found.

Answer 1

Number 4 is the right answer

Answer 2

I believe the answer is #4. u can always ask google if u believe that's the wrong answer :)
