v = d/t

v1 = x2 – x1/ t2 – t1

v2 = x3 – x2/ t3 – t2

a = vf – v0 / t

a = v / t

a = v – v0/ t – t0 = v / t

a = v / t = v/t

d = 1/2 . t . a =1/2 . a . t2

x = xf – xi

x1 = xf1 – x0

x2 = xf2 – x0

v = v2 – v1

v = v – v0

t = t – t0

at = v – v0

V – V0 = at

V = V0 + at

d 1 = v0 t

d2 = ½ (v – v0) . t

d2 = ½ (at) . t = ½ at2

d = d1 + d2 = v0t + ½ at2

vmt = v0t + ½ at2 = (v0 + 1/2at) .t

vm = v 0 + ½ at = 2v0 + at/ 2

vm = 2v0 + v – v0/2 = v0 + v/2

v = v0 – at

d = v0t – ½ at2

dd = v0td – ½ at2d;

g = 9.8 m/ s2

g = 10 m/ s2

t = v/g

d = ½ gt2

2d = gt2

2d/g = t2

t2 = 2d/ g

t = √(2d/g)

v = v0 - gt

h = v0t – ½ gt2

0 = v0 – gts

ts = v0/g

h max = v0ts -1/2 gt2s= v0 vo/g -1/2 g (v0/g)2

h max = v02/ 2g

tb = √(2h max/g ) = √(2.v20/2g/g) = √(v20/g2) = v0/g = ts

t aire = ts + tb = v0/g + v0/g = 2v0/g
