JEE Main 2009 Physics question
A motor cycle starts from rest and accelerates along a straight path at 2 . At the starting point of the motor cycle there is a stationary electric sire. 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 )
Answer: (2)
Solution
Observer receding from a stationary source: \frac{v}{330}$) = 0.94f
