Question

Two spectators at a soccer game see, and a moment later hear, the ball being kicked on the playing field. The time delay for spectator $A$ is $0.23 \mathrm{~s}$, and for spectator $B$ it is $0.12$ s. Sight lines from the two spectators to the player kicking the ball meet at an angle of $90^{\circ} .$ How far are (a) spectator $A$ and (b) spectator $B$ from the plaver? (c) How far are the spectators from each other?

00:01 We are given that there are two spectators, spectator a and spectator b.
00:09 They are watching a football match.
00:12 Now a player kicked a ball, kicked the ball.
00:18 So the first spectator, both the spectators first see the ball kicking and then hear the sound of the kicking.
00:27 So this time delay for spectator a is 0 .23 second and time delay for spectator b is 0 .1 2 second.
00:45 And the side lines from the two spectators to the player make 90 degree angle...
