Next, based on the correct answer from part a, which of the following is the correct symbolic expression for a?
(a) m(a1 + f)/(2m)
(b) (a1 + f)/m
(c) (ma1 + f)/m
(d) (ma1 + f)/(2m)

would be false hope this out

they should be similar or the same

2b2t

explanation:

2b2t

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
