Question

What is the momentum of a car with a mass of 1,900 kg moving at a constant velocity of 20 m/s?
(1 point)
0 kg.m/s
40,000 kg.m/s
95 kg.m/s
38,000 kg.m/s

Answer 1

Momentum is calculated using the formula:

\[
\text{Momentum} (p) = \text{mass} (m) \times \text{velocity} (v)
\]

Given:
- Mass (\(m\)) = 1,900 kg
- Velocity (\(v\)) = 20 m/s

Now, plugging in the values:

\[
p = 1,900 \, \text{kg} \times 20 \, \text{m/s} = 38,000 \, \text{kg.m/s}
\]

So, the momentum of the car is **38,000 kg.m/s**.
