The solid fuel of a 300.kg rocket travelling at 1.64x104 km/h is ignited to correct the rocket trajectory in midflight to Mars. 10.00 kg of fuel is burnt in 15.00 s. If the exhaust velocity of the fuel, relative to the rocket, is 2.90x103 km/h, what is the acceleration of the rocket (in m/s2) at the start of this burn?
