A stranded soldier shoots a signal flare into the air to attract the attention of a nearby plane. The flare has an initial verti
Ipatiy [6.2K]

Answer:

Explanation:

h = ut - 16 t² = ut - 1/2 x32 t² = ut - 1/2 g t² , g = acceleration  = - 32 ft / s²

1) v² = u² - 2 g h , v = 0 so

h = u² / 2g = 1500² / 2 x 32 = 35156.25 ft

2) v = u - gt

t = u / g = 1500 / 32 = 46.875 s

3) It will hit the ground after 2 x 46.875 = 93.75 s

4 ) time to reach 30000 ft height  t is given by

h = ut - 16 t²

30000 = 1500t - 16t²

16t²-1500t + 30000 = 0

t = 28.92 s  and 64.82 s

Time required to travel 50000 by plane

= 50000/880 = 56.82 . There is no match of timing so plane will not hit it.

Suppose a particle is accelerated through space by a constant 10-N force. Suddenly the particle encounters a second force of 10-
Harlamova29_29 [7]

Answer:

The particle will continue moving at constant velocity

Explanation:

When the particle encounters the second force of 10 N, the net force acting on the particle becomes zero, because the two forces are equal in magnitude but opposite in direction:

F_{net}=10 N-10 N=0

For Newton's second Law, the acceleration of the particle is proportional to the net force acting on it:

F_{net}=ma

Therefore, since F_{net}=0, the acceleration is zero (a=0) and so the particle will keep a constant velocity.

There are 1,660 megawatts of wind-generated electricity produced globally every year. This amount is equivalent to A. 1,660,000
disa [49]
Let us first write down the known things .

1660 megawatts = 1660 X 10^6 watt
                           = 166000 kilowatt

From the above deduction we can conclude that the correct option among all the options that are given in the question is the second option or option "B". I hope that this is the answer that you were looking for and the answer has actually come to your desired help.
