Determine A and B from the equation v(t)=A*t+B*t^2.?

A 2250-kg test rocket is launched vertically from the launch pad. Its fuel (of negligible m) provides a thrust force so that its vertical velocity as a function of time is given by v(t)=A*t+B*t^2, where and are constants and time is measured from the instant the fuel is ignited. At the instant of ignition, the rocket has an upward acceleration of 1.10 m/s^2 and 2.00s later an upward velocity of 2.33m/s .
