A bomber moving horizontally with 500m//...

A bomber moving horizontally with `500m//s` drops a bomb which strikes ground in 10s. The angle of strike with horizontal is

A

` tan ^(-1) (1/5)`

B

`90^@`

C

`tan^(-1) (1)`

D

`tan ^(-1) (5)`

Text Solution

Verified by Experts

The correct Answer is:
A
`v_(x)=500m//s.`
`v_(y)=-gt =-10(10)=-100m//s` angle with horizontal `=tan^(-1) (v_(y)/v_(x))=tan^(-1) (1/5)`
