a) vf = gt
b) h = 1 / 2 g t2
c) VF2-VI2 = 2GH
and when you release the body from a height h, we have that vi = 0, then
2GH vf = Root
Note: In the fall of bodies of air resistance increases with the rate of fall. In the first few seconds the resistance is small and grows with increasing speed, until after a certain time is equal to the weight of the body and the acceleration vanishes, ie, from that moment the body reaches its limit speed, continuing the fall with uniform motion.
