Answer:
C) Newton's law of inertia
Step-by-step explanation:
The law states that a body will continue in its state of rest or uniform motion unless compel by some external forces (acted upon by an unbalanced force) to act otherwise. In this case the golf will remain in it state because the downward force of gravity is equal to the upward force of normal and the horizontal vector sum of the forces acting on the body is zero.
