Question

If you drop an object from a height of 0.9 m, it will hit the ground in 0.44 s. If you throw a baseball horizontally with an initial speed of 39 m/s from the same height, how long will it take the ball to hit the ground

Answer 1

So, when an object is dropped from a height of 0.9 meters, it takes approximately 0.428 seconds to hit the ground.

\Now, let's consider the horizontally thrown baseball. The vertical motion is independent of the horizontal motion, so the time it takes to hit the ground will be the same. Therefore, it will take the baseball approximately 0.428 seconds to hit the ground when thrown horizontally with an initial speed of 39 m/s from the same height.
