Two spectators at a soccer game see, and a moment later hear, the ball being kicked on the playing field. The time delay for the spectator A is 0.55 s, and for the spectator B it is 0.45 s. Sight lines from the two spectators to the player kicking the ball meet at an angle of 90°. The speed of sound in the air is 343 m/s. How far are (a) spectator A and (b) spectator B from the player?
(c) How far are the spectators from each other?

a)188.65m

b)154.35m

c)243.7m

Explanation:

Given data:

(a) The distance from the kicker to each of the 2 spectators is given by:

where,

v= speed of sound

=time taken for the sound waves to reach the ears

m

(b)

where,

v= speed of sound

=time taken for the sound waves to reach the ears

(c)As the angle b/w slight lines  from the two spectators to the player is right angle,

hypotenuse=the distance b/w 2 spectators

and, the slight lines are the other 2 lines

it is because acrylic blanket have acrylic textile fiber

explanation:

its is better than wool blanket

the answer for apex is the lowest
