A car starting from rest, accelerates at a constant rate x for sometime after which it decelerates at a constant rate v to come to rest. If the total time elapsed is t, the maximum velocity attained by the car is given by –
  • $\frac{x y}{x+y} t$
  • B
    $\frac{x y}{x-y} t$
  • C
    $\frac{x^2 y^2}{x^2+y^2} t$
  • D
    $\frac{x^2 y^2}{x^2-y^2} t$

Answer
