Question

a ball falls 80 m free fall what is the final velocity

Answer 1

i know vi and a and y

Answer 2

2as=v^2-u^2

Answer 3

about 1600 m/s

Answer 4

Vf= Under Root of 1600 i.e 40 m/s

Answer 5

sorry 4 dat silly ..........actually my net had gone off

vsquare = 1600 and v= 40......

Answer 6

velocity in free fall
\[V= \sqrt {2gH}= \sqrt {2*10*80}=40m/s\]
