A rocket is launched vertically. In the first 2 seconds after launching, the rocket loses 160 \frac{1}{60} of its weight. The velocity of the gas released from the rocket is 3600 ms−1 3600 \mathrm{~ms}^{-1} . Determine the net acceleration of the rocket. (Assume g= \mathrm{g}= 9.8 ms−2 9.8 \mathrm{~ms}^{-2} )
