Question

16. In a game of T-ball, two batters hit a ball that is placed on a tee.

Batter A swings the bat from a resting position on his shoulder
Batter B places the bat directly behind the ball and pushes it forward without swinging
Based on this information, answer the following question:

In the T-ball scenario, how does Newton's Second Law of Motion help explain why one batter hits the ball farther than the other?

Responses

The bat applies an equal and opposite force to the ball, so both batters hit it the same distance
The bat applies an equal and opposite force to the ball, so both batters hit it the same distance

The ball stays in motion until friction slows it down, so both batters hit it far

The mass of the bat doesn’t matter; only the angle of the swing affects the distance

The faster the bat moves, the greater the force on the ball, causing it to travel farther

18. A boy pushes a heavy box across the floor with constant force, but the box moves slowly. According to Newton’s Second Law of Motion, which of the following will help the boy make the box move faster?(1 point)
Responses

Decreasing the mass of the box

Applying less force to the box

Keeping the same force but pushing in a different direction

Answer 1

16. The faster the bat moves, the greater the force on the ball, causing it to travel farther.
- A faster bat delivers a larger impulse/force to the ball (F = ma), producing greater acceleration and speed so the ball goes farther.

17. The ball will stay at rest until it is kicked.
- Newton’s First Law: an object at rest remains at rest unless acted on by a net external force.

18. Decreasing the mass of the box.
- From F = ma, for the same push (F) reducing the mass (m) increases acceleration, so the box moves faster.
