A8.8kg object undergoes an acceleration of 2.2 meters per sonds squared what is the magnitude of the resulting force acting on it

F = m a

Force = (mass) (acceleration)

Force = (8.8 kg) (2.2 m/s²)

Force = (8.8/2.2) (kg-m/s²)

Force = 4 Newtons.

That's the force that MUST ACT on the 8.8 kg object IN ORDER TO make it accelerate it at the rate of 2.2 m/s² .  We don't know where the force comes from or what caused it.  It may not even be a single force.  It may be a whole bunch of forces that all add up to 4 Newtons in one direction.  We only know that if it were not there, then the object WOULD NOT accelerate at 2.2 m/s².

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
