Practice objective / multiple choice question 20 from the 2020 Waec Model Questions Vol1 Mathematics examination.
The time \(t\) (in seconds) taken for a particle to travel a distance \(s\) (in metres) under a constant force \(F\) (in newtons) varies directly with \(\sqrt{s}\) and inversely with \(F\). If it takes 8 s to travel 16 m when the force is 4 N, how long will it take to travel 25 m when the force is 9 N? Give your answer as a fraction in simplest form.
