A car is moving along a frictionless surface with a speed of 2 m/s to the left. You and your friend each come over and push the car at the same time. You exert a force of 6 N to the left, while your friend exerts a force of 6 N to the right. According to Newton's first law, how will this action affect the car's motion? The car will speed up because your force is in the same direction of the car's motion, making it speed up. The car will stop immediately because two balanced forces will cause an object to stop moving. The car will continue moving to the left but at a slower speed because your friend's force is going to make the car slow down. The car will continue to move 2 m/s to the left because there are balanced forces acting on it.

Study the scenario.
A car is moving along a frictionless surface with a speed of 2
m/s to the left. You and your friend each come over and push
the car at the same time. You exert a force of 6 N to the left,
while your friend exerts a force of 6 N to the right.
According to Newton's first law, how will this action affect the
car's motion?
The car will speed up because your force is in the
same direction of the car's motion, making it speed
up.
The car will stop immediately because two balanced
forces will cause an object to stop moving.
The car will continue moving to the left but at a
slower speed because your friend's force is going to
make the car slow down.
The car will continue to move 2 m/s to the left
because there are balanced forces acting on it.

Expert Solution
Step 1

Force is a vector quantity and we have to add it using law of vector addition.

F = m a 

F is total external force.

m is mass.

a is acceleration.

a = d v / d t .
