A) \[45\,\,m\]
B) \[50\,\,m\]
C) \[40\,\,m\]
D) None of these
Correct Answer: A
Solution :
We know that,\[h=ut+\frac{1}{2}g{{t}^{2}}\] \[\because \] \[u=0\] \[\therefore \] \[h=\frac{1}{2}g{{t}^{2}}\] \[=\frac{1}{2}\times 10\times {{(3)}^{2}}\] \[=5\times 9\] \[=45\,\,m\]You need to login to perform this action.
