A ball is thrown horizontally from the top of a building 53.8 m high. The ball strikes the ground at a point 119 m from the base of the building. The acceleration of gravity is 9.8 m/s. The time (I got this answer and it's correct and all) is 3.3135sec. (part 2 of 4) Find the initial velocity of the ball. (part 3 of 4) Find the x component of its velocity just before it strikes the ground. 007 (part 4 of 4) 10.0 points Find the y component of its velocity just before it strikes the ground. vaverage = d/t a = Vdelta/t vf = vi + at I don't even know any others -_- I tried to use vf^2 = vi^2 + 2ad??????? It didn't work. I am really lost but if someone could tell me which formula (kinematics) to use that would be great. I already got the time (part 1 of 4) to equal 3.3135sec but despite using the right equations etc I can't get the other three parts.
