A toy car of mass 100 g is moving with a constant velocity of 0.5 m s⁻¹. What is the net force acting on the toy car? [Pg. No. 106]

Mass of toy car,

$$m = 100 \text{ g} = 0.1 \text{ kg}$$

Velocity is constant, so acceleration $a = 0$.

Using Newton's second law:

$$F = ma$$

$$F = 0.1 \times 0 = 0$$

Therefore, the net force acting on the toy car is 0 N.
