A boy can throw a stone up to a maximum height of `10 m`. The maximum horizontal distance that the boy can throw the same stone up to will be :

Options

A. `20sqrt(2) m`
B. `10m`
C. `10 sqrt(2) m`
D. `20m`

Answer

D

Explanation

`H_(max) = (u^(2))/(2 g) rArr 10 = (u^(2))/(2 g) rArr (u^(2))/(g) = 20`
`R_(max) = (u^(2))/(2 g) = 20 m`
