Ignore the 2nd half of the question at first (the player 48.5m away).
You need to find the range of the football. Work that out first.
After that compare that distance to where the player is. i.e. find the distance between where the ball lands and 48.5m.
Then remember that the ball is kicked and the player runs at the same time. So they both take the same time to get to the spot where the ball lands.
See if you can work it out now.
A soccer ball is kicked from the ground with an initial speed of 19.4 m/s at an upward angle of 49.8˚. A player 48.5 m away in the direction of the kick starts running to meet the ball at that instant. What must be his average speed if he is to meet the ball just before it hits the ground? Neglect air resistance.
