Question

Study the scenario.

A toy car is pushed across the floor with a force of 4 N to the right. There is 1 N of friction acting on the car to the left.

What is the net force acting on the car?

0.25 N
5 N
4 N
3 N

Answer 1

3N

This is because unbalanced opposite forces form a resultant force (as an object can’t move in 2 different directions) so the 4N to the right And 1N on the left form a resultant force as the smaller force is taken from the larger force 4N-1N to form a resultant force of 3N to the right.

Answer 2

The net force acting on the car is 3 N.

(d) is correct option.

Step-by-step explanation:

Given that,

Force = 4 N to the right

Friction force = 1 N to the left

We need to calculate the net force acting on the car

According to the question,

When a toy car is pushed across the floor with a force then the normal force applied to the right and the frictional force applied to the left on the car.

Then, the net force = normal force - frictional force

Using formula of net force

`F_(net)=F-F_(k)`

`F_(net)=4-1`

`F_(net)=3\ N`

Hence, The net force acting on the car is 3 N.
