Question

de una ventana que esta a una altura de 12m se cae una maceta

Answer 1

Datos
Vi=0
h=12m
g=9.8m/s^2
Vf=?
Solución
Vf^2=Vi^2+2gh
Vf^2=2gh
Vf=raíz[2gh]
Vf=raíz[2(9.8m/s^2)(12m)]
Vf=raíz[235.2m^2/s^2]
Vf=15.33m/s

V=Vi+gt
V=gt
t=V/g
t=(15.33m/s)/(9.8m/s^2)
t=1.56s

Answer 2

Vf^2=Vi^2+2gh
Vf^2=2gh
Vf=raíz[2gh]
Vf=raíz[2(9.8m/s^2)(12m)]
Vf=raíz[235.2m^2/s^2]
Vf=15.33m/s

V=Vi+gt
V=gt
t=V/g
t=(15.33m/s)/(9.8m/s^2)
t=1.56s
