Answer:
F'=708.53 N
Explanation:
We have,
The lifting force, F, exerted on an airplane wing varies jointly as the area, A, of the wing's surface and the square of the plane's velocity, v. It means tat,
k is constant
If, A = 190 Ft², v = 220 mph, F = 950 pounds
Let's find k first from above data. So,
It is required to find the lifting force on the wing if the plane slows down to 190 miles per hour. Let F' is the new force. So,
So, the lifting force is 708.53 pounds if the plane slows down to 190 miles per hour.

<em>Average velocity is defined as the ratio of change in position to the time taken for that change. </em>
Answer: <em>True</em>
Explanation:
Velocity is obtained by dividing the displacement of an object by time interval. Displacement is a vector quantity which is defined as the shortest distance between initial and final point of an object.
In other words, displacement is the change in position of an object. A position-time graph can be plotted to find the average velocity of an object graphically. The average velocity can be obtained by calculating the slope of the position-time graph.
While average velocity deals with velocity over a particular time interval, instantaneous velocity gives the velocity of an object at a particular point of time or instant.
