 If all three pitches (A, B, and C) had equal amounts of KE when they left the pitcher's hand, would they all have the same amount of KE when they reach home plate?

• Yes, because they all end at home plate

• No, because they have different forces acting on them

• Yes, because they start with the same amount of KE

• There is not enough information to answer this question

 If all three pitches (A, B, and C) had equal amounts of KE when they left the pitcher's hand, which pitch will have the highest amount of KE left when it gets to home plate?

• Pitch A, because it has the most amount of Force from the wind acting against it

• Pitch A, because it has the least amount of Force from the wind acting against it

• Pitch C, because it has the most amount of Force from the wind acting against it

• Pitch CA, because it has the least amount of Force from the wind acting against it

 If all three pitches (A, B, and C) had equal amounts of KE when they left the pitcher's hand, which pitch will have the lowest amount of KE left when it gets to home plate?

• Pitch A, because it has the most amount of Force from the wind acting against it

• Pitch A, because it has the least amount of Force from the wind acting against it

• Pitch C, because it has the most amount of Force from the wind acting against it

The data following table shows how fast a major league power hitter can swing a bat with different amounts of mass. The mass of the bat was the independent variable in this investigation, and the speed of the bat swing was the dependent variable.

Which column should you assume is the X-AXIS?

• Mass of the bat (grams)

• Bat swing speed (mph)
