Two cars P and Q start from a point at the same time in a straight line and their positions are represented by \(\mathrm{x}_{p}(\mathrm{t})=\mathrm{at}+\mathrm{bt}^{2}\) and \(x_{0}(t)=t-t^{2}\). At what time do the cars have the same velocity?
- \(\frac{a+f}{2(1+b)}\)
- \(\frac{f-a}{2(1+b)}\)
- \(\frac{a-f}{l+b}\)
- \(\frac{a+f}{2(b-1)}\)
Answer
(B) f-a 2(1+b)
