A) \[4.5\sqrt{2}m{{s}^{-1}}\]
B) \[5\,m{{s}^{-1}}\]
C) \[5\sqrt{32}m{{s}^{-1}}\]
D) \[1.5\,m{{s}^{-1}}\]
E) \[1\,m{{s}^{-1}}\]
Correct Answer: A
Solution :
\[{{(1\times v)}^{2}}={{(3\times 1.5)}^{2}}+{{(3\times 1.5)}^{2}}\] \[\Rightarrow \] \[v=4.5\sqrt{2}m/s\]You need to login to perform this action.
