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`

Text Solution

Verified by Experts

The correct Answer is:
B
`R=u_(x)tTrArr u_(x)=(R)/(T)=(200)/(5)=40m//s`
