A missile is fired for maximum range with an initial velocity of `40m//s`. If `g=10m//s^(2)`, the range of the missile is

Text Solution

Verified by Experts

The correct Answer is:
D

`Deltavecv=vecv_("top")-vecv_(1)`
`(u cos theta)hati-[(u cos theta)hati+(u sin theta)hatj]=-(u sin theta) hatj`
`|Deltavecv|=u sin theta`
change in speed `=(u cos theta)-v`
