Neco Model Questions Vol1 2018 Mathematics Question 25
Practice objective / multiple choice question 25 from the 2018 Neco Model Questions Vol1 Mathematics examination.
The time \(t\) (in seconds) required for a particle to travel a distance \(s\) (in metres) under a certain force varies directly as \(\sqrt{s}\) and inversely as the cube of its speed \(v\) (in m\,s\(^{-1}\)). If it takes 8 s to travel 200 m at a speed of 4 m s\(^{-1}\), how long will it take to travel 450 m at a speed of 6 m s\(^{-1}\)? Give your answer to two decimal places.
