6. Los amortiguadores de un automóvil viejo con masa de 1800 kg están gastados. Cuando una persona de 780 N se sube lentamente al auto en su centro de gravedad, el auto baja 5.0 cm.
Cuando el auto, con la persona a bordo, cae en un hoyo, comienza a oscilar verticalmente en
un movimiento armónico simple. Considere el auto y la persona como un solo cuerpo (una sola
masa) en un solo resorte y calcule (a) el periodo y (b) la frecuencia de oscilación. (10 puntos)

c)as speed changes, wavelength and frequency change.

everything changes!

answer: b.

explanation:

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
