Neco Model Questions Vol1 2020 Physics Question 37
Practice objective / multiple choice question 37 from the 2020 Neco Model Questions Vol1 Physics examination.
An ambulance siren emits sound of frequency \(800\,\text{Hz}\). An observer standing on a road hears the frequency as \(880\,\text{Hz}\) as the ambulance approaches, and later \(733\,\text{Hz}\) as it recedes. Assuming the speed of sound in air is \(340\,\text{m\,s}^{-1}\) and the observer is stationary, calculate the speed of the ambulance (in \(\text{m\,s}^{-1}\)).
