Question 1

A cyclist accelerates uniformly from rest. After 4.0 s, the cyclist has travelled 32 m. At exactly 4.0 s, the cyclist passes a stationary observer. What distance will the cyclist travel in the next 2.0 s?

Question 4

A cyclist accelerates uniformly from rest along a straight road. After \(8.0\) s, the cyclist reaches a velocity of \(12.0\) m s\(^{-1}\). The cyclist then maintains this constant velocity for a further \(15.0\) s before applying the brakes and decelerating uniformly to rest over a distance of \(54.0\) m. Calculate the total distance travelled by the cyclist from the initial start to coming to rest. Show your working.
