Problem 2 - (25 points) A disk of mass Mand radius R rolls without any significant drag at velocity v across a flat surface. It then encounters an incline at angle 0 above the horizontal
and rolls up the incline. To what height, h, does the disk reach before it stops and turns
around? Write your formula using terms of OM, R, v and g as needed. The rotational inertia
of a disk is 12 MR.

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
