A large airplane (plane A) flying at 26,000 feet sights a smaller plane (plane B) travelling at an altitude of 24,000 feet. The

Answer:

The line of sight distance is 1285.58 feet.

Step-by-step explanation:

The situation is illustrated in the figure attached.

From the figure we see that the altitude difference of the planes and the distance between them form a right triangle with one angle of 40° .

The line of sight between the two planes is the hypotenuse of the triangle.

The altitude difference of the planes is

$26,000ft -24,000ft = 2000 ft.$

Therefore, if we call $x$ the line of sight distance, from trigonometry we have

$sin (40^0) = \frac{2000ft}{x}$

$\boxed{ x = 1285.58ft}$

Therefore, the line of sight distance (x) is 1285.58 feet.

alexandr402 [8]

Answer:

6.7 /s.

Step-by-step explanation:

Initial velocity = u m/s

From the question, final velocity, v = - 2u m/s

Note - (the minus sign indicates that the direction was reversed and doubled)

t = 0.45

From equation of motion,

v = u + at

Acceleration, a = (v - u)/t

= (-2u - u)/0.45

= - 3u/0.45

Acceleration, a/Original speed, u = 3/0.45

= 6.7 /s
