Answer:
34.8 m/s
Explanation:
Since we're only interested in vertical velocity we can ignore anything horizontal.
We have the following information (in the vertical direction)
d = 61.8
a = 9.8
vi = 0
vf = ?
The equation combining all these variables is:
[tex]v_f^2 = v_i^2 + 2ad\\v_f^2=0+2(9.8)(61.8)\\v_f^2=1211.28\\v_f=\sqrt{1211.28}\\v_f=34.8[/tex]
