A soccer player is 15 m from her opponent's goal. she kicks the ball hard; after 0.50s, it flies past a defender who stands 5m away, and continues toward the goal. How much time does the goalie have to move into position to block the kick from the moment the ball leaves the kickers foot?

Sagot :

Answer:

Explanation:

ASSUMING the defender at 5 m is NOT the goalie.

the ball horizontal velocity is 5 m/0.5 s = 10 m/s

The goalie, presumably at the goal line, has 15 m / 10 m/s = 1.5 s to react and move to the ball position.

Must be little league soccer as 10 m/s is a rather wimpy soccer ball speed.
