A) \[11/40\,m{{s}^{-2}}\]
B) \[22/40\,m{{s}^{-2}}\]
C) \[1.1/40\,m{{s}^{-2}}\]
D) \[1\,m{{s}^{-2}}\]
E) \[11/60\,\,m{{s}^{-2}}\]
Correct Answer: A
Solution :
Acceleration, \[a=\frac{\Delta m}{\Delta t}.\frac{u}{\left( m-\frac{\Delta m}{\Delta t}.t \right)}\] \[=10\times \frac{11}{(1000-10\times 60)}\] \[=\frac{11}{40}m/{{s}^{2}}\]You need to login to perform this action.
