Professional baseball player nolan ryan could pitch a baseball at approximately 160.0 km/h. at that average velocity, how long did it take a ball thrown by ryan to reach home plate, which is 18.4 m from the pitcher’s mound? compare this with the average reaction time of a human to a visual stimulus, which is 0.25 s.

0.41 s

Explanation:

Parameters given:

Speed of ball, v = 160 km/h

Distance between Ryan and the home plate, d = 18.4 m = 0.0184 km

Speed is given as the time rate of change of distance. Mathematically:

Therefore, time will be:

The time it will take the ball to reach the home plate is 0.41 s.

Comparing this to the average reaction time of humans to visual stimulus (0.25 s), we see that the time it will take the ball is greater than the reaction time.

This implies that an average person should be able to track the motion of the ball as it moves towards the home plate.
