Igcse Model Questions Vol1 2017 Physics Question 2
Practice objective / multiple choice question 2 from the 2017 Igcse Model Questions Vol1 Physics examination.
A train horn emits a sound of frequency \(500\ \text{Hz}\). An observer on the platform hears a frequency of \(526\ \text{Hz}\) as the train approaches, and later hears \(476\ \text{Hz}\) as the train recedes. Assuming the speed of sound in air is \(340\ \text{m s}^{-1}\), determine the speed of the train. Express your answer as a fraction of the speed of sound and also in \(\text{m s}^{-1}\) to two significant figures.
