Technically friction is acting on the car because it is still rubbing against the street and gravity is pulling the car down preventing it from floating??? lol
We know follwing formula
F=a*m
where F is RESULTANT force, a is acceleration and m is mass. We can transform that formula to obtain a, so
F=a*m /:m divide both sides by m
Now we have to calculate resultant force acting.
We know that Dale and Alex push on opposite direction so we have to put minus in front on one of the forces and add it.
40+(-32)=40-32=8 [N] - resultant force acting on the couch
Now we have all necessary date, we can substitute.
a=
- its the result
Hey there! :D
Force is energy or strength that as the characteristic of movement or physical action.
A push or pull is a force. It moves something physically. If I was going to push a door for it to open, I would physically be moving it.
Inertia is a common tendency to remain unchanged or do nothing. If you are not doing anything, you are not applying force or movement to anything. This would not be the correct answer. We can eliminate "C" and "E"
Since a push and pull both are a force, then "D" is the answer. They both are.
I hope this helps!

Answer:
(a) Position Vectors V₁= -2î km, V₂=5î km
(b) Displacement Δx=7 km
Explanation:
Given data
Distance=2 km west at t=0
Distance=5 km east at t=6 min
Positive x is the east direction
To find
(a)Car position vector at given times
(b)Displacement between 0 to 6.0 min
Solution
For Part (a) car position vector at given times
At t=0 the distance=2 km west so conclude that x₁=-2 because it is in negative side So vector V₁
V₁= -2î km
At t=6.0 the distance=5 km east so conclude that x₂=5 because it is in positive side So vector V₂
V₂=5î km
For (b) displacement between 0 to 6.0 min
According to following mathematical law we can conclude that
Δx=x₂-x₁
Δx=5-(-2)km
Δx=7 km
