A stone is thrown at an angle `theta` to the horizontal reaches a maximum height H. Then the time of flight of stone will be:

A

`sqrt((2H)/(g))`

B

`2sqrt((2H)/(g))`

C

`2sqrt((2Hsintheta)/(g))`

D

`sqrt((2Hsintheta)/(g))`

Text Solution

Verified by Experts

The correct Answer is:
B

By using `s=vt-(1)/(2)at^(2)` , we get
`H=0-1/2(-g)((T)/(2))^(2)rArrT=2sqrt((2H)/(s))`

A particle is projected from the ground with velocity u at angle theta with horizontal. The horizontal range, maximum height and time of flight are R,H and T respectively. They are given by, R = (u^(2)sin 2 theta)/(g),H = (u^(2)sin^(2)theta)/(2g) and T = (2usin theta)/(g) Now keeping u as fixed, theta is varied from 30^(@) to 60^(@) . Then,
