Total length of the board = 30 inch
Length of,
-- First piece = x
-- Second piece = 4x
-- Third piece = 5x
5x + 4x + x = 30
10x = 30
x = 3
Therefore, the lengths of:
-- First piece = 3 inch
-- Second piece = 4*3 = 12 inch
-- Third piece = 5*3 = 15 inch
we can use formula
where
fL is listener frequency
fs is siren frequency
va is the speed of sound in air
vs is police car speed
so, we have
now, we can change it into m/s
now, we can plug it
