Question

a soccer player practices kicking the ball into the goal from halfway down the soccer field. the time it takes for the ball to get to the goal from the time it is kicked averages about three seconds. the soccer field is 90 meters long. the player wants to know the average velocity of the ball. is there enough information to calculate this? a. yes, we have enough information. b. no, we need the displacement. c. no, we need the direction. d. no, we need the time.

Explanation:

Step1: Recall velocity definition

Velocity is a vector quantity, which requires both magnitude and direction.

Step2: Analyze given information

We know the distance (half of 90 meters) and time (3 seconds), but no direction is given.

Answer:

C. No, we need the direction.
