Answer:
5 ft/s²
Explanation:
u = Initial velocity = 100 ft/s
v = Final velocity = 0
s = Displacement = 1000 ft
a = Acceleration
From equation of motion
The airplane's deceleration is 5 ft/s² or 1.524 m/s²
The diagram represents Earth in its orbit around the Sun and the Moon (M) in different positions in its orbit around Earth. Lett
ers A through D represent four positions of Earth in its orbit. Earth is closest to the Sun near position D and farthest from the Sun near position B. Identify the lettered position of Earth and the Moon when this full moon phase can be observed, and state the name of the eclipse that could occur at this position.

For a curved mirror, the radius of curvature R is twice the focal length f:
(1)
Since the diameter d is twice the radius R, we can rewrite (1) as
From which we can calculate the focal length from the diameter:
