Answer 1

To determine the force with which the toy car was pushed, you can use Newton's second law of motion, which states:

\[
F = m \cdot a
\]

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

Given:
- \( m = 5 \, \text{kg} \)
- \( a = 3 \, \text{m/s}^2 \)

Substituting the values into the equation:

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

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