A) \[512\,\,m\,\,{{s}^{-1}}\]
B) \[215\,\,m\,\,{{s}^{-1}}\]
C) \[341\,\,m\,\,{{s}^{-1}}\]
D) \[651\,\,m\,\,{{s}^{-1}}\]
Correct Answer: C
Solution :
\[\Rightarrow \upsilon =\frac{\text{Distance}}{\text{Time}}=\frac{78.4\,\,m}{0.23\,\,s}=341\,\,m\,\,{{s}^{-1}}\]You need to login to perform this action.
