Aspace telescope travels about earth in a circular orbit at a distance of 380 miles from earth's surface. it makes one orbit every 95 minutes. find its linear velocity in miles per hour. (the radius of earth is approximately 3960 miles.) round to the nearest tenth place.

17217.44 miles per hour

Explanation:

h = 380 miles

T = 95 minutes = 1.583 hours

Radius of earth, r = 3960 miles

Let v be the linear speed.

v = 17217.44 miles per hour

Thus, the speed of the telescope is 17217.44 miles per hour.

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
