Every body continues in a state of rest or uniform motion in a straight line unless acted on by a resultant external force. That's approximately Newton's first law of motion.
So, the velocity of something tends to remain the same, unless an external force changes it. This is sometimes called "inertia". A body at rest, as in with "no velocity" will tend to remain at rest, unless there's a force on it. inertia again.
Answer:
Horizontal component of velocity = 241.61 m/s
Explanation:
Given that,
Velocity of a jetliner is 245 m/s
The vertical component of the plane's velocity is 40.6 m/s,
We need to find the magnitude of the horizontal component of the plane velocity.
The resultant velocity is given by :
Where, is the horizontal component of the plane velocity
So, the magnitude of the horizontal component of the plane velocity is 241.61 m/s.
