Question

Would a ball thrown with the speed of 20m/s off of the top of a 55 meter high building land at least 60 meters away from the building? How far away would it land?

Answer 1

Ignoring air resistance . . .

-- A ball starting from 55 meters off the ground takes 3.35 seconds to hit the ground.

-- If it's moving horizontally at 20 m/s, then in 3.35 seconds it gets

(20 m/s) x (3.35 sec) = 67 meters away from the building.

Answer 2

No. The ball would not end up 60 meters away. The ball will end up 65 meters away because of the force thrown with the ball. I believe I'm right.
