a pitcher throws a fastball horizontally toward home plate 18.39 meters away. If the ball is traveling at a speed of 40.0m/s, neglecting air friction, how long does it take for the ball to get to home plate

It will take 0.46 seconds to reach home plate by ball.

Explanation:

A pitcher throws a fastball horizontally toward home plate 18.39 meters away, so horizontal displacement = 18.39 meter.

The ball is traveling at a speed of 40.0 m/s, so horizontal velocity = 40.0 m/s

We know that displacement = Velocity * Time

So time required, T = Displacement/Velocity = 18.39/40 = 0.46 seconds

It will take 0.46 seconds to reach home plate by ball.
