A Comparison Between Two Falling Balls

The Scenario

A student throws a heavy red ball horizontally from a balcony of a tall building with an initial speed v0. At the same time, a second student drops a lighter blue ball from the same balcony. Neglecting air resistance, which statement is true?

The Options

1. The blue ball reaches the ground first.
2. The balls reach the ground at the same instant.
3. The red ball reaches the ground first.
4. Both balls hit the ground with the same speed.
5. None of the above statements is true.

Without air resistance, both balls reach the ground at the same instant. Neither horizontal motion nor weight affects vertical motion.
