Answer:

1. a golf ball striking the ground is a collision

2. the ground exerts an equal force on the golf ball

Step-by-step explanation:

1. a golf ball striking the ground is a collision

That is certainly a collision because the two bodies here exert a contact force on each other for a relatively short time.

2. the ground exerts an equal force on the golf ball

According to Newton's Third Law when body A exerts a force on body B then B exerts an equal but opposite force on A. So the ground exerts an equal (in magnitude) but opposite (in direction) force on the ball
