Formula: a= F/m
F= mxa
m=Fla
1. A little boy pushes a wagon with his dog in it. The mass of the dog and wagon together is 50 kg. The wagon accelerates at 0.85 m/

4. A crate is dragged across an ice covered lake. The box accelerates at 0.08m/s2 and is pulled by a 45 N force. What is the mass of the box?
5.3 women push a stalled car. Each woman pushes with a 400N force. What is the mass of the car if the car accelerates at 0.85 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

i believe the answer is electric potential.
