Answer:
Newton's First Law of Motion.
Explanation:
Newton's first law of motion states that an object continues to stay in its state of rest, or of uniform motion, until acted upon by an external force.
So in the case of the golf ball here, the ball stays in its state of rest, on the tee, until the golf club hits it, i.e. , applies an external force on it.
Hence we can say that Newton's First Law of Motion is the principle which is most suitable for explaining this phenomenon.
Heya!!
For calculate aceleration, lets applicate second law of Newton:

<u>Δ Being Δ</u>
F = Force = 78,3 N
m = Mass = 24,5 kg
a = Aceleration = ?
⇒ Let's replace according the formula and clear "a":

⇒ Resolving

Result:
The aceleration is <u>3,19 meters per second squared (m/s²)</u>
Good Luck!!
The answer is a newton second law
Answer:
True
Explanation:
If it weren't from a 90 degree angle then the circle would be a bit more oval shaped
