The use of an approved scientific calculator is expected where appropriate. Answer all questions. There are thirty questions in this section. For each question there are four possible answers A, B, C and D. Choose the one you consider correct and record your choice in soft pencil on the separate Answer Sheet. Each correct answer will score one mark. A mark will not be deducted for a wrong answer. Any rough working should be done in this booklet. This document consists of 19 printed pages and 1 blank page.

It travels for some time at this constant speed and then has a uniform deceleration of 0.40 m s−2 until it comes to a rest at the next station. The distance between the two stations is 3000 m. What is the time taken by the train to travel between the two stations? A 75 s B 150 s C 225 s D 300 s
