The resuhant of the vectors A and B depends also on the angle `theta` between them.The magnitude of the resultant is always given by

Options

A. `A+B+2AB costheta`
B. `sqrt(A+B+2ABcostheta)`
C. `sqrt(A^2+B^2+2ABcostheta)`
D. `(A^2+B^2+ costheta)^2`

Explanation

`t=sqrt((2h)/g)`
Distance =`vxxtimpliesv+D/t`
`t=D/sqrt((2h)/g)`
`:.t=Dsqrt(g/2h)`
