A particle is thrown vertically upwards its velocity at half of the height is 10 m/s then the maximum height attained by it is `( g= 10 m//s^2)`

A

`8 m`

B

`20 m`

C

`10 m`

D

`16m`

Text Solution

Verified by Experts

The correct Answer is:
C
from equation of motion `, v^2 = u^2 +2as`
` O= (10)^2 +2 2(-10) s `
` S=5 m`
` u= 10 ms^(-1) `
` v=0 ms^(-1)`
` a=- 10 ms^(-2)`
total height `= 2xx5= 10 m`
