Question

A bomber moving horizontally with `500m//s` drops a bomb which strikes ground in 10s. The angle of strike with horizontal is
A. `sin^(-1)(1/5)`
B. `tan^(-1)(1)`
C. `tan^(-1)(1/5)`
D. `tan^(-1)(5)`

Answer 1

Correct Answer - c
`tan theta=(v_(y))/(v_(x))=("gt")/(v_(x))=(10xx10)/500=1/5`
i.e, `theta=tan^(-1) (1/5)` with horizontal
