Answer 2

Given:

Force, F = 70 N

Frictional force, f = 20 N

To Find:

The net force applied on the toy car.

Calculation:

- The force of friction always acts opposite to the motion.

- So when a force F is applied on the toy car, the frictional force f will act against it.

- So the net force is given as:

Net Force = F - f

⇒ Net Force = 70 - 20

⇒ Net Force = 50 N

- So, the net force applied on the toy car is 50 N.
