Two objects are launched with the same initial horizontal velocity, but one has twice the initial vertical velocity as the other. Which of the following statements is true?

Question

One has twice the total speed as the other
They have the same acceleration
They have the same max height
One travels twice as far as the other.

Answer 1

C
The horizontal speed does not affect the vertical speed, so both rise to the same height.

Just as when you drop one rock and throw the other horizontally. They both hit the ground at the same time.
