A) 3.0\[m{{s}^{-1}}\]
B) 5.7\[m{{s}^{-1}}\]
C) 3.82\[m{{s}^{-1}}\]
D) 2.86\[m{{s}^{-1}}\]
Correct Answer: D
Solution :
\[{{a}_{1}}{{v}_{1}}={{a}_{2}}{{v}_{2}}\] \[\Rightarrow \] \[4.20\times 5.18=7.60\times {{v}_{2}}\] \[\Rightarrow \] \[{{v}_{2}}=2.86\,\,m/s\]You need to login to perform this action.
