To solve the problem, we need to understand what principle of physics is demonstrated by the statement: "The golf ball remains at rest until it is struck by a golf club."
Explanation:
This statement reflects the concept of inertia, which is a fundamental part of Newton's First Law of Motion.
Newton’s First Law of Motion (Law of Inertia):
A body at rest will remain at rest, and a body in motion will remain in uniform motion in a straight line, unless acted upon by an external force.
In this case, the golf ball remains stationary (at rest) until an external force—the swing of the golf club—is applied to it.
Final Answer:
The statement indicates Newton’s First Law of Motion (Law of Inertia).
If \[ A = \begin{bmatrix} 1 & 2 & 0 \\ -2 & -1 & -2 \\ 0 & -1 & 1 \end{bmatrix} \] then find \( A^{-1} \). Hence, solve the system of linear equations: \[ x - 2y = 10, \] \[ 2x - y - z = 8, \] \[ -2y + z = 7. \]
