Problem

Object P moves with a constant velocity of

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

, while object Q starts from rest with a constant acceleration of

2\,\text{m s}^{-2}

. Both start simultaneously from the same point along a straight track. After how many seconds will they have travelled equal displacements from the starting point? a)

2.5\,\text{s}

10\,\text{s}

5\,\text{s}

\sqrt{5}\,\text{s}\;(\approx 2.24\,\text{s})
