Problema 1
Dos ciudades A y B están separadas por una distancia 1200 Km. Desde A sale
hacia B un móvil con velocidad constante de 50 Km/h. una hora y media después
sale desde B hacia A otro móvil con velocidad constante de 85 Km/h. calcular
donde y cuando se encuentran.

Problema 2
Dos ciudades A y B están separadas por una distancia 5500 m. Desde A parte del
reposo un móvil hacia B con una aceleración de 0.8 m/seg2. Simultáneamente
sale desde B hacia A otro móvil con aceleración de 1.4 m/seg2 calcular donde y
cuando se encuentran. Calcular la velocidad final de cada móvil.

the focus of lesson 1 is newton's first law of motion - sometimes referred to as the law of inertia. newton's first law of motion is often stated as. an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

explanation:

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day

find the sum of the two horizontal vectors and the sum of the two vertical vectors
