If a particle is confined to move on a spherical surface of radius a, 7 to denote its position vector, then show that the projection ormal ê, is always (a) (5 poi and we use of the acceleration d2r/dt2 along the instantaneous surface - (dr/dt)/a. ) suppose the particle is executing a uniform circular motion along a latitude on the surface of our (spherical) earth of radius a. its speed is u. what itude and direction of its instantaneous centripetal acceleration? (c) (2 points) show that parts (a) and (b) are self-consistent.

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
