I have a single plank of wood that is 6 meters long, and a rock I can use as a fulcrum. I make a lever with a mechanical advantage of 2. I place an 80N bottle on the output end of this lever. With how much force will I have to push on the input end in order to lift this bottle?
Draw and label a diagram that shows this lever. Label the input and output arms, as well as the fulcrum. Draw the 80N bottle on the output arm.

i think if it were me i whould divide 300 dide 15

step-by-step explanation:

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
