A motor cycle starts from rest and accelerates along a straight path at \[2\,\text{m}{{\text{s}}^{-2}}\]. At the starting point of the motor cycle there is a stationary electric siren (in m). When the driver hears the frequency of the siren at 94% of its value, the motor cycle was at rest then distance travelled by the motor cycle is _____ m. (Speed of sound \[=330\,\text{m}{{\text{s}}^{-1}}\]).
