Questions About Normal Force and Golf Putting

[BuBbLeS01]

I don't understand the normal force and how to calculate it. If I have a question about a golfer putting a ball with a speed and a force that s slowing it down to get to the hole, it has normal force but it would equal 0 because there is no movement in the y direction right?

Normal force is a contact force: two objects must be touching for it to be present. In your problem, the ball is on the ground. As you say, there is no vertical movement. So what is true about the vertical (y-direction) acceleration of the ball? What would be the net vertical force on the ball?

Now, what forces are acting on the ball in the vertical direction? Would this imply that the normal force on the golfball is zero?
