Unit | Assignment: Conceptual Experiment Worksheet प
A college student named Nova walked 500 meters for 500 seconds from her dormitory building to find her
favorite bench in a park. She called her mom and talked for 100 seconds at the bench, but suddenly she
remembered that she did not turn off the gas stove. So, she returned her dorm by running for 100
seconds. To find out Nova's average velocity for each case while walking, resting, and running, begin by:
plotting a graph between position and time.

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
