A missile is fired for maximum range with an initial velocity of `20m//s`. If `g=10m//s^(2)`, the range of the missile is

A

`40 m`

B

`50 m`

C

`60 m`

D

`20 m`

Text Solution

Verified by Experts

The correct Answer is:
A
(a): `u=20m//s, g=10m//s^(2)`
For maximum range , angle `theta=45^(@)`
`R_("max")=(u^(2))/(g)=(20xx20)/(10)=40m`
