A 0.50 kg ball traveling at 6.0 m/s collides head on with a 1.00 kg ball traveling -12.0 m/s. After the collision, the 0.50 kg ball
moves away at -14 m/s. What is the velocity of the second ball after the collision?
after the collision?

a lot of it means it can be "burned" for energy and sold at one price. if it is scarce, the price will go up

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
