Calculate the acceleration of a car if its velocity increases from 2.0 m/s to 6.4 m/s in 4.0s

1.1 m/s²

Explanation:

a = (v – v₀) / t = (6.4 – 2.0) / 4.0 = 1.1 m/s²

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete

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
