Problem

A cyclist starts from rest, quickly reaches

5\,\text{m s}^{-1}

, and then continues to accelerate uniformly along a straight road. The speed of the cycle increases from

5\,\text{m s}^{-1}

15\,\text{m s}^{-1}

while covering a distance of

100\,\text{m}

. (a) Calculate the magnitude of the uniform acceleration during this stage. (b) Find the time taken by the cycle to cover the

100\,\text{m}

distance.
