Question

Louisa and her husband are pushing their car to a gas station. At one point, the forces acting on a the car are the following: a gravitational force of 12,200 N downward, a normal force of 12,200 N upward, Louisa's pushing force of 330 N eastward, her husband’s pushing force of 310 N eastward, and a friction force of 440 N westward. Which of the following statements is accurate?
Select one:

a.
There is a net force of 25,480 N acting on the car.
b.
There is a net force of 1080 N acting on the car.
c.
There is no net force acting on the car.
d.
There is a net force of 200 N acting on the car.

Answer 1

Answer:

d.

There is a net force of 200 N acting on the car.

Explanation:

Weight and normal forces are balanced in the vertical

In the horizontal there is 640 N acting eastward and 440 N acting westward for a net force of 200 N eastward.

Which is quite unfortunate as g••gle maps says the closest fuel is 1.2 km Southwest.

Answer 2

In this exercise, we will compute the net force exerted on the car including that of Louisa and her husband who are pushing their car to a gas station.

Given data

Vertical forces

Gravitational force of 12,200 N downward, = -12,200 N

Normal force of 12,200 N upward = +12,200 N

Total  = 0 N

Horizontal forces

Louisa's pushing force of 330 N eastward = + 330 N

her husband’s pushing force of 310 N = +310 N

Total = +640N

Frictional force

Friction force of 440 N westward = -440N

Total = -440N

Hence the summation of all forces will be =  0 +640 -440 =  200 N

Hence There is a net force of 200 N acting on the car.
