You drive in a straight line at 12 m/s for 1.5 min, then stop for 3.5 min, then drive at 15 m/s for 2.5 min. (a) plot x(t). (b) find average velocity for entire drive. 1. a stone is thrown vertically up and reaches maximum height 10 m. (a) find initial speed of the stone. (b) plot the graph of velocity versus time for the entire flight. 2. sition a bedy is given by x=34+2f' for tue osts a) pcof x (t); ) find average ve locity e's

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
