1.	A car starting from rest, accelerates at a constant rate x for sometime after which it decelerates at a constant rate y to come to rest. If the total time elapsed is t, the maximum velocity attained by the car is given by
Answer» (a) `(XY)/(X+y)t` (B) `(xy)/(x-y)t` (C) `(x^(2)y^(2))/(x^(2)+y^(2))t` (d) `(x^(2)y^(2))/(x^(2)-y^(2))t`
