Question

jennifer runs through an obstacle course at summer camp. which statement describes how newton’s first law of motion is involved in this interaction? as jennifer darts to the right around an obstacle, her hair momentarily remains in place until it’s pulled to the right along with her. the ground exerts the same forward force on jennifer as jennifer exerts backward on the ground. jennifer accelerates more than the ground she pushes on because jennifer is less massive than the ground.

Explanation:

Newton's first law, or the law of inertia, states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. When Jennifer darts to the right, her hair (an object at rest relative to her initial motion) remains in place initially due to inertia until it is pulled along with her. The second statement is Newton's third - law (action - reaction), and the third statement is related to Newton's second law ($F = ma$).

Answer:

As Jennifer darts to the right around an obstacle, her hair momentarily remains in place until it's pulled to the right along with her.
