A) \[2.5\text{ }m/{{s}^{2}}\]
B) \[5.0\text{ }m/{{s}^{2}}\]
C) \[10\text{ }m/{{s}^{2}}\]
D) \[25\text{ }m/{{s}^{2}}\]
Correct Answer: A
Solution :
Acceleration of the block \[a=\frac{F}{m}\] \[a=\frac{1}{m}\frac{P}{t}\] \[=\frac{1}{m}.\frac{m'v}{t}\] where\[\frac{m'}{t}=\]rate of releasing of water = 1 kg/s \[\therefore \] \[a=\frac{1}{2}\times 1\times 5\] \[=\frac{5}{2}=2.5m/{{s}^{2}}\]You need to login to perform this action.
