You throw a rock horizontally out of a 7th story window. You time that it takes 3.7 seconds to hit the ground, and measure that it hit the ground 115 m from the base of the building. What is the height of the 7th floor window?
PLZ HURRY YA MAN DOES NOT HAVE THAT LONG!!!!!!!!!!!
Since we are only looking at the vertical height, we can use the free fall equation to find the height: h = 0.5*g*t^2, where h is height in m, g is acceleration due to gravity (9.81 m/s^2), and t is time in seconds h = 0.5*(9.81 m/s^2)*(3.7 s)^2 h = 67.15 m Therefore, the 7th floor window is 67.15 m above ground level.
