Solutions

Expert Solution

Answer(b).

Yes, we are accelerating but upward instead of downward.

Answer (c).

As the club-swing , the potential energy due to the swinging become kinetic enegy and  then this kinetic energy transferred to the ball on contact.

Answer(e).

we need a follow through on the swing to make sure we hit the ball with as much power and force as we can. Also, the amount of force we used to hit the ball makes it impossible to stop right after hitting the ball without taking away from the power of the swing or hurting.

Answer(f).

When hooking a golf shot the ball is starting off (for right handed golfers) going to the right and curving severely to the left.

By turning our whole body on the down swing and not just sliding our hips we can get more of a hook.

Answer(g).

Sweet spot is the exact point on the face where, when you strike a golf ball, the centr of gravity (CoG) of the club head is moving directly towards the CoG of the golf ball. If you strike the ball with the sweet spot of the club, with a square club face and path, the ball will fly straight and true and will travel the maximum distance.

Answer(h).

The club made an unpleasantly loud, tinny sound when it struck the ball which is called PING. It produced when the bottom of the club head (called the sole) vibrated at frequencies that fell smack in the most sensitive range of human hearing.
