Let’s solve and discuss maths questions together.
I will try to post one question every day with answer in the following 52*7+2 days, without any solution. Everyone is welcomed to post questions too, but this is not a homework thread -.-
(I do not set a specific topics or difficulty for the questions, but try to add interesting questions or solutions to here.)

Please post your full solution after 12 hours so we can leave time for the others to solve.

If a ball, that is 6 meters above the ground, is thrown perfectly horizontally to the right, how long would it take to reach the ground? (Assume gravity is 9.81m/s)

and also, how far, horizontally, would the ball travel after reaching the ground?

USE THE METRIC SYSTEM PEOPLE

cuz nobody likes the Imperial/English System aside from the Americans
