A player kicks a ball at a speed of 20ms...

A player kicks a ball at a speed of `20ms^(-1)` so that its horizontal range is maximum. Another players 24m away in the direction of kick starts running in the same direction at the same instant of hit. If he has to catch the ball just before it reaches the ground, he should run with a velocity equl to `(take g=10ms^(-2))`
