Neco 2023 Physics Question 35
Practice objective / multiple choice question 35 from the 2023 Neco Physics examination.
A particle starts from rest and moves in a straight line with an acceleration that is proportional to time: \(a(t)=k\,t\) (in \(\text{m s}^{-2}\)), where \(k\) is a constant. After travelling a distance of \(90\ \text{m}\) its speed is measured to be \(18\ \text{m s}^{-1}\). Determine the elapsed time (in seconds) from the start to the instant when the particle has covered the 90 m.
