A motor cycle starts from rest and accelerates along a straight path at

2m/{s^2}.

At the starting point of the motor cycle there is a stationary electric siren. How far has the 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\,m{s^{ - 1}}

)
