A car accelerates at the rate of \(\mathrm{m} / \mathrm{s}^{2}\) for some time and then decelerates at \(\beta \mathrm{m} / \mathrm{s}^{2}\) for the rest of the time. The maximum velocity attained during the total journey which took time t is
- \((x+\beta) t\)
- \(\left(\frac{\pi \beta}{\pi+\beta}\right)\)
- \(\left(\frac{\pi \beta}{\beta-\pi}\right) t\)
- None of these
Answer
(C) ( - ) t
