You lower a bundle weighing 64.0 kg to the ground with a rope that will snap if the tension exceeds 578.2 N. If the height is 8.0 m and you barely avoid snapping the rope, what speed will the bundle hit the ground?

Tension=mgma
solve for a. Then, speed equals
Vf^2=2a*8 
I still don't get it. I got 3.5 which is not the right answer

nevermind the answer is 3.50
