To find the force applied to the toy car, we can use Newton's second law of motion, which states:

\[ F = m \times a \]

Where:
- \( F \) is the force in Newtons (N),
- \( m \) is the mass in kilograms (kg),
- \( a \) is the acceleration in meters per second squared (m/s²).

Given:
- Mass \( m = 5 \) kg,
- Acceleration \( a = 3 \) m/s².

Now we can substitute the values into the formula:

\[ F = 5 \, \text{kg} \times 3 \, \text{m/s}^2 = 15 \, \text{N} \]

Therefore, the force with which the toy car was pushed is **15N**.
