A 35 kg boat is moving at a constant speed. Then a 7 N force is applied. After some time, the boat is moving much faster. What is the acceleration of the boat?

• 5 m/s²

• 0.2 m/s²

• Higher than 0.2 m/s², because the boat was already moving

• Higher than 5 m/s², because the boat was moving faster after some time

• A) Newton's First Law

• B) Newton's Second Law

• C) Newton's Third Law

• D) Newton's Laws do not explain why this happens.

A baseball player hits a baseball with a bat, causing it to fly across the field. Three actions occur during this event:

1. The ball moves toward the batter at a constant velocity.

2. The ball hits the bat and then flies in the opposite direction.

3. The ball moves with an acceleration proportional to the force applied by the batter and the mass of the ball. Which of the following pairs each event with the Law that it describes?

• 1: Newton’s First Law; 2: Newton’s Second Law; 3: Newton’s Third Law

• 1: Newton’s Second Law; 2: Newton’s First Law; 3: Newton’s Third Law

• 1: Newton’s Third Law; 2: Newton’s Second Law; 3: Newton’s First Law

• 1: Newton’s First Law; 2: Newton’s Third Law; 3: Newton’s Second Law
