Question

Alguien me puede resolver esto por favor es urgente

Answer 1

SOLUCIÓN :

2) DATOS :

Vx = 2 m/seg R= 3.5 m

tv=?

h=?

SOLUCIÓN :

R = Vx* tv

tv = R/Vx = 3.5 m/2 m/seg = 1.75 seg

tv = 1.75 seg .

h = g * tv²/2

h = 10m/seg²* ( 1.75 seg)²/2

h = 15.31 m.

3) Datos :

Vx =1.5 m/seg

h = 1.2 m tv= ? R =?

SOLUCIÓN :

h = g *tv²/2

tv = √( 2*h/g)

tv =√( 2*1.2 m/10 m/seg²)

tv = 0.48 seg

R = vx* tv = 1.5 m/seg * 0.48seg = 0.72 m .
