A motor cycle starts from rest and accelerates along a straight path at \( 2 \mathrm{~m} / \mathrm{s}^{2} \). At the starting point of the motor
\( \mathrm{P} \) cycle there is a stationary electric siren. How far has the W motor cycle gone when the driver hears the frequency of the siren at \( 94 \% \) of its value when the motor cycle was at rest (Speed of sound \( =330 \mathrm{~ms}^{-1} \) )
[AIEEE 2009]
(a) \( 49 \mathrm{~m} \)
(b) \( 98 m \)
(c) \( 147 m \)
(d) \( 196 m \)
