Question
A student is standing on top of the school building (which they shouldn’t be doing) and has a height of 78.4m. They kick a rock off the edge of the building with a velocity of 6 m/s.
How long does it take the rock to fall?
How far away from the base of the building does the rock land?

flight time (t)
78.4 = 1/2 * g * t^2 ... t = √(2 * 78.4 / g)
horizontal distance = 6 m/s * t
78.4 = 1/2 * g * t^2 ... t = √(2 * 78.4 / g)
horizontal distance = 6 m/s * t
