Answer:
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

Answer:
The wavelength in miles is <u>0.1165 miles</u>.
Explanation:
Given:
Wavelength of the radio wave is 187.37 m.
Now, the wavelength is given in meters.
We need to convert the wavelength from meters to miles.
In order to convert meters to miles, we have to use their conversion factor.
We know that,
1 meter = 
Therefore, the conversion factor is given as:

So, the wavelength in miles is given as:

Hence, the wavelength in miles is 0.1165 miles.

Answer:
3.95979 m/s
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration

Here 


Initial velocity of the puck should be 3.95979 m/s
