A player kicks a football obliquely at a speed of `20 m//s` so that its range is maximum. Another player at a distance of `24m` away in the direction of kick starts running at that instant to catch it, the speed with which the second player has to run is `(g=10 ms^(-2))`

A

`4 m//s`

B

`4sqrt2 m//s`

C

`8sqrt2 m//s`

D

`8 m//s`

Text Solution

Verified by Experts

The correct Answer is:
B
`R_(max)=u^(2)/g` , distance `=R_(max)-x`
`T=(2usintheta)/g` , Distance `=VxxT`
