A golf ball is released from rest from teh top of a very tall building. Choose a coordinate system whose origin is at the starting point of the ball, and whose y axis points vertically upward. The acceleration of gravity is 9.8 m/s^2. Neglecting air resistance , calculate the velocity of the ball after 2.84s. ANswer in units of m/s.(adsbygoogle = window.adsbygoogle || []).push({});

---ok basically i have tried this question about 3 times and each time i have gotten it wrong. The first two answers made absolutely no sense and the third answer i got was 185.3543

this is how i did it:

Vf= 9.8m/s^2(2.84s)^s

= 60.27392

then i did

60.27392^2= 2(9.8 m/s^2x)

i got 185.3543

----

please reply asap i have no clue how to solve this- i thought i was correct but apparently not. what formulas should i use? How would i go about to getting the answer? THANKS SO MUCH
