Answer 1

To calculate the momentum of the toy car, we first need to determine its velocity. The formula for velocity is:

\[
\text{Velocity} = \frac{\text{Distance}}{\text{Time}}
\]

Given:
- Distance = 1.23 meters
- Time = 3.2 seconds

Calculating the velocity:

\[
\text{Velocity} = \frac{1.23 \text{ m}}{3.2 \text{ s}} \approx 0.384375 \text{ m/s}
\]

Next, we calculate the momentum using the formula:

\[
\text{Momentum} = \text{Mass} \times \text{Velocity}
\]

Given:
- Mass = 0.33 kg
- Velocity ≈ 0.384375 m/s

Calculating the momentum:

\[
\text{Momentum} = 0.33 \text{ kg} \times 0.384375 \text{ m/s} \approx 0.126 \text{ kg.m/s}
\]

Rounding to the nearest hundredth:

\[
\text{Momentum} \approx 0.13 \text{ kg.m/s}
\]

Thus, the answer is:

**0.13 kg.m/s**
