Gce Model Questions Vol1 2017 Physics Question 50
Practice objective / multiple choice question 50 from the 2017 Gce Model Questions Vol1 Physics examination.
A police siren emits sound of frequency \(800\,\text{Hz}\). The siren is mounted on a car that moves in a straight line towards a stationary observer. When the car is approaching, the observer hears a frequency of \(880\,\text{Hz}\). After the car passes the observer and recedes, the observer hears a frequency of \(735\,\text{Hz}\). Assuming the speed of sound in air is \(340\,\text{m s}^{-1}\), determine the speed of the car (in \(\text{m s}^{-1}\), to two significant figures).
