Runner A begins a \(100\)-meter race at time \(t = 0\) and runs at a constant speed of \(6.0\,\text{m/s}\). Runner B starts the same race \(3\) seconds later but runs at \(9.0\,\text{m/s}\).(a) Does Runner B catch up before the finish line? , (b) If so, at what time and distance does this happen? , (c) Who finishes the race first, and by how much time? :

\(\text{Yes}\) \(t = 9\,\text{s},\; \Delta x = 54\,\text{m}\) \(\text{Runner B, }2.56\,\text{s}\)
