A motorcycle starts from rest and accelerates along a straight line at 2.81 m/s2,
on a day when the speed of sound is 343 m/s. A siren is located at the starting
point and remains stationary. How far has the motorcycle gone when the driver
hears the frequency of the siren at 90% of the value it has when the motorcycle
is stationary.
