Question

9 fill in the blank 0.5 points if the ball and air are pushing each other with the same amount of force, why does the ball slow down as it moves through the air? since the mass of the ball is the same as the mass of the air, the force applied on the ball will cause it to have more acceleration than the air. this will cause it to slow down. 10 after the ball moves through the air, it hits the ground and rolls through the grass. newton explains the action / reaction pair in his choose your answer law by stating the choose your answer pushes on the choose your answer with the same amount of force as the choose your answer pushes back on the choose your answer

Explanation:

For question 9, according to Newton's second law $F = ma$ (force equals mass times acceleration), with equal forces, the object with less mass has more acceleration. Air has much less mass than the ball, so the ball experiences more deceleration (negative acceleration) due to air - resistance. For question 10, Newton's third law states that for every action, there is an equal and opposite reaction. When the ball hits the ground and rolls through the grass, the ball pushes on the ground/grass and the ground/grass pushes back on the ball with the same amount of force.

Answer:

1. Since the mass of the ball is greater than the mass of the air, the force applied on the ball will cause it to have more (negative) acceleration than the air. This will cause it to slow down.
2. Newton explains the action/reaction pair in his third law by stating the ball pushes on the ground/grass with the same amount of force as the ground/grass pushes back on the ball.
