A large number of bullets are fired in all directions with same speed v. what is the maximum area on the ground on which these bulles will spread?

A

`pi((2u^(2))/(g))^(2)`

B

`3pi((u)/(g))^(2)`

C

`5pi((u)/(2g))^(2)`

D

`pi((u^(2))/(g))^(2)`

Text Solution

Verified by Experts

The correct Answer is:
D
`R_("max")=(u^(2))/(g)`
area `=piR_("max")^(2)=pi[(u^(2))/(g)]^(2)`

A big Diwali rocket is projected vertically upward so as to attain a maximum height of 160 m. The rocket explodes just as it reaches the top of its trajectory sending out luminous particles in all possible directions all with same speed v.
