Neco Model Questions Vol1 2022 Physics Question 36
Practice objective / multiple choice question 36 from the 2022 Neco Model Questions Vol1 Physics examination.
A source emits sound of frequency (800\ \text{Hz}\) in air where the speed of sound is (340\ \text{m\ s^{-1}}\). The source moves directly towards a stationary observer with speed \(v_s\). At the same time the observer moves directly away from the source with speed \(20\ \text{m\ s^{-1}}\). The observer measures a frequency of \(880\ \text{Hz}\). Find the speed \(v_s\) of the source (in \(\text{m\ s^{-1}}\), to one decimal place).
