A body is thrown vertically upward with velocity `u`, the greatest height `h` to which it will rise is,
A
`u // g`
B
`u^(2) // 2g`
C
`u^(2)//g`
D
`u//2g`
Text Solution
Verified by Experts
The correct Answer is:
C
Given, initial velocity = u, height = h and a = g (acceleration due to gravity) At the highest point, final velocity becomes zero i.e., v = 0 From , third equation of motion, `v^(2) = u^(2) - 2gh` `0 = u^(2) - 2gh` `2gh = u^(2)` `rArr h = (u^(2))/(2g)` Here, we have used negative sign because the body is moving against the gravity.
