Question

An arrow is shot into air. Its range is 200m and its time of flight is 5s. If `g = 10 ms^(-2)`. If `g = 10ms^(-2)`, then horizontal component of velocity and the maximum height will be respectively
A. `25m//s`
B. `40m//s`
C. `31.25 m//s`
D. `12.5m//s`

Answer 1

Correct Answer - B
`R=u_(x)tTrArr u_(x)=(R)/(T)=(200)/(5)=40m//s`
