Igcse Model Questions Vol1 2020 Mathematics Question 15
Practice objective / multiple choice question 15 from the 2020 Igcse Model Questions Vol1 Mathematics examination.
The time \(t\) (seconds) taken for a particle to travel a distance \(s\) (metres) varies directly with \(s\) and inversely with \(\sqrt{F}\), where \(F\) (newtons) is a constant force. When \(s=20\) m and \(F=4\) N the time is \(t=5\) s. Find the time required to travel \(s=45\) m when the force is increased to \(F=9\) N.
