Igcse Model Questions Vol1 2021 Mathematics Question 15
Practice objective / multiple choice question 15 from the 2021 Igcse Model Questions Vol1 Mathematics examination.
The time \(t\) (seconds) taken for a particle to travel a distance \(s\) (metres) under a constant force varies directly as \(\sqrt{s}\) and inversely as the speed \(v\) (m\,s$^{-1}$). If it takes 8\,s to travel 20\,m when the speed is 4\,m\,s$^{-1}$, find the time required to travel 45\,m when the speed is 6\,m\,s$^{-1}$.
