A) \[\sqrt{{{u}^{2}}-2gh}\]
B) \[2gh\]
C) \[\sqrt{2gh}\]
D) \[\sqrt{{{u}^{2}}+2gh}\]
Correct Answer: D
Solution :
Since, velocity is vector quantity, its horizontal component is \[u\]and vertical component is v and from equation of motion \[v=\sqrt{2gh}\] Taking the resultant of \[u\]and \[v\] \[R=\sqrt{{{u}^{2}}+{{v}^{2}}}\] \[=\sqrt{{{u}^{2}}+2gh}\]You need to login to perform this action.
