A book is sitting on a table. jackie is pushing the book with a force of 9 N to the right. if the force of friction is 4 N to the left, what is the net force? 1. 5 N right
2. 4 N left
3. 5 N left
4. 4 N right

1

Explanation:

4+5 =9

5n to the right

net force = 5 Newtons

Explanation:

here's the solution :-

=》net force = force exerted - friction

=》net force = 9N - 4N

=》net force = 5 N

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
