Hi Guys this is the problem I am stuck at:(adsbygoogle = window.adsbygoogle || []).push({});

The solid fuel of a 420.0 kg rocket traveling at 18100.0 km/hr is ignited to correct the rocket trajectory in mid-flight to Mars. 5.00 kg of fuel is burnt in 13.0 s. If the exhaust velocity of the fuel, relative to the rocket, is 3650.00 km/hr, what is the acceleration of the rocket (in m/s2) at the start of this burn?

I tried momentum conservation and unable to end up with correct accl of Rocket.

Thanks a lot
