Miniature golf is a game in which players hit a golf ball with a club, which causes the ball to roll along the flat ground. Three golf balls with the same mass were rolling on the ground. Each ball was hit by a golf club, but not from the same direction. All the golf balls changed speed as a result of being hit. Use the information in the diagram to answer.

Which golf ball(s) experienced the strongest force when hit? How do you know?

a
The white and purple golf balls because they gained force, while the green golf ball lost force.

b
The green golf ball because it takes a stronger force to slow something down than to speed something up.

c
The green golf ball because it changed speed the most.

d
The white golf ball because it has the fastest ending speed.

Answers

Answer: The blue and white golf balls; they have more mass than the yellow golf ball, but changed speed by the same amount.
