At the top of a building you and a friend throw two identical baseballs exactly horizontal away from the building releasing the ball at exactly the same time. Your friend throws the baseball twice as fast as you.

a)friends ball hits the ground after yours but goes twice as far
b) your friends ball hits the ground after yours and goes 1.5 as far
c) your friends ball hits the ground at the same time as yours, and goes twice as far d)your friends ball hits the ground at the same time as yours and goes twice the distance

Option C

your friends ball hits the ground at the same time as yours, and goes twice as far

Explanation:

The vertical speed is the same but the horizontal speed of your friend is twice yours. This implies the time to hit the ground is the same but after hitting the ground since the horizontal speed of your friend is twice, then the ball moves a horizontal diatance twice yours. Therefore, option C is correct.
