A 100 kg man stands on bathroom scale inside an elevator, on planet where free fall acceleration is 10 m. s^2. Elevator which was initially at rest starts moving moving down with constant acceleration 5 m/s^2. Reading of the scale is

I think its 500. Let me know if its right. I need to show my teacher that I answered 5 students questions for my college assignment

Explanation:

f is prop to m1xm2 double m1 double force

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
