Ask Your Teacher A constant force of 2.0 N to the right acts on a 20.0 kg mass for 0.35 s. (a) Find the final velocity of the mass if it is initially at rest. .035 Correct: Your answer is correct. m/s (b) Find the final velocity of the mass if it is initially moving along the x-axis with a velocity of 1.31 m/s to the left.

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
