Question

You drop a package from an airplane flying at a constant speed in a straight horizontal line. From the same height and time, one red ball is dropped and another blue ball is fired horizontally. The air resistance can be neglected. Which will hit the ground first, the package, the red ball, or the blue ball?

Include an explanation!

Answer 1

All three objects will hit the ground at same time.

all of them are falling vertically under the influence of gravity. They fall from the same height. Therefore, they will hit the ground at the same time

*the plane and the package have the same horizontal horizontal velocity at the moment of release. They will maintain this velocity in the x-direction only

*the “fired” ball(blue) also has a horizontal velocity.“fired” ball has a larger net velocity but still in freefall they hit the ground same time
