How far from the base of the building does the ball hit the ground?

A ball is thrown horizontally from a 13m -high building with a speed of 5.0 m/s. How far from the base of the building does the ball hit the ground? I know delta y =.5gt^2 but I still can’t figure it out. Can someone please take me step by step?

To find out how far something travels in the x direction, we need to know how long it is going for. The only way to do this is to figure out how long it will take to drop off a 13m building. For that first step, to find the time, we will use the kinematics equation:h = .5gt^2 << you had that part, good jobUsing algebra, we get that:t = √((2h) / g)Plug in our values:t = √(26 / 10) = √2.6 = 1.6s (roughly)Now, with 1.6 seconds with which to fall, we use the equation:d = vtPlug in our values: d = (5)(1.6) = 8m...
