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?

Respuesta :

I think so. Half of 90 is 45 so 45 divided by 3 (3 seconds) if 15. 15 meters per second.

Soccer player practices kicking the ball

The player has 15 meters per second ( m/s ) average velocity of the ball. In order to calculate, we know that the formula of calculating the velocity is velocity = displacement / time.

A player practices kicking the ball into the goal from halfway down the soccer field. Half displacement will be considered which is 45 meters and time interval is given which is 3 seconds. By putting values in the formula v = d / t ( 45 / 3 ) = 15, we get 15 m / s average velocity.
