A rock is thrown horizontally at a speed of 80ft/sec from the top of a building that is 64 ft high.
A) How long does it take for the rock to hit the land?
B) How far from the base of the building will the rock land?
C) At what speed does the rock hit the land?
My answers so far are:
a) t = 1.995 seconds to hit ground
b) rock will land 48.68 meters (or 159.62 feet) away from the base of the building
c) Haven't finished solving but I keep getting v^2 = -358.68 m/s which is impossible... Unless it means 358 m/s in the opposite direction, which DOES make sense, since velocity is a vector which has direction and magnitude.
