A rocket initially at rest accelerates with constant net acceleration B from t = 0 to t = T1 at which time the fuel is exhausted. Neglect air resistance. If the rocket's net acceleration, B, is equal to 1.0g, find an expression for the total time [itex] T_{max} [/itex] (from liftoff until it hits the ground).(adsbygoogle = window.adsbygoogle || []).push({});

So [tex] T_{max} = T_{1} + t [/tex]

[tex] \frac{1}{2}BT_{1}^{2} + BT_{1}t - \frac{1}{2}gt^{2} = 0 [/tex]

I know that [tex] t = \frac{BT_{1}}{g} [/tex]

What do I do from here? I got [tex] T_{max} = 2T_{1} = 2 t [/tex]

Thanks
