A) \[\text{28}.\text{7 m}/{{\text{s}}^{\text{2}}}\]
B) \[\text{34}.\text{9 m}/{{\text{s}}^{\text{2}}}\]
C) \[\text{39}.\text{4 m}/{{\text{s}}^{\text{2}}}\]
D) \[\text{27}.\text{8 m}/{{\text{s}}^{\text{2}}}\]
Correct Answer: B
Solution :
Here, \[\frac{dm}{dt}=16\,\,kg/\sec ,\,\,u=11\,\,km/\sec \] \[{{m}_{0}}=6000\,\,kg\] and \[t=1\min =60\sec \] \[\therefore \]Acceleration, \[a=16\times \left[ \frac{11000}{(6000-16\times 60)} \right]\] \[=\mathbf{34}\mathbf{.9}\,\,\mathbf{m/}{{\mathbf{s}}^{\mathbf{2}}}\]
