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

Answer

D

Explanation

`h_(max) = (u^(2))/(2g) = 10 ( :' theta = 90^(@))`
`rArr u^(2) = 200 rArr R_(max) = (u^(2))/(g) = 20 m`
