A) \[\sqrt{\frac{2h}{g}}\]
B) \[\sqrt{\frac{h}{g}}\]
C) \[2\sqrt{\frac{h}{g}}\]
D) \[4\sqrt{\frac{h}{g}}\]
Correct Answer: A
Solution :
From the equation of motion \[h=ut+\frac{1}{2}g{{t}^{2}},\] We get \[h=0+\frac{1}{2}gt_{0}^{2}\] \[{{t}_{0}}=\sqrt{2h/g}\]You need to login to perform this action.
