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 $$ = 330\,m{s^{ - 1}}$$)
