You throw a ball horizontally off of a building with a horizontal velocity of 10 m/s. What is the ball’s horizontal velocity 5 seconds later? How high should the building be if you want the ball to fall for a total of 10 seconds?

Answer 1

Vh = 10m/s and is constant.

h = Vo*t + 0.5gt^2,
h = 0 + 4.9(10)^2 = 490m.
