Two people are pushing a car. One person is pushing with a force of 450 N and the
other person is pushing with a force of 300 N. What information is needed to
determine the net force applied to the car by the people?
the direction of the road
the direction of the forces
the weight of the two people
the weight of the automobile

Answer 1

the direction of the road

Explanation:

To calculate the net force, we need to know the direction through which the forces are acting.

Are the forces directed towards one another or against each other?

Net force is a vector sum of forces that acts on a body. It is that single force that can replace two or more forces acting on a body.

• If the forces are against each other, we subtract them.
• If they act on a body together, we add them.

So, without knowing the direction, we cannot calculate the net force.
