Question

p_{pencil} = -0.2 kg m/s p_{pen} = -0.6 kg m/s
what is the total momentum
of the system?

Explanation:

Step1: Recall total momentum formula

To find the total momentum of a system with multiple objects, we sum their individual momenta. The formula for total momentum \( P_{total} \) is \( P_{total} = P_{pencil} + P_{pen} \).

Step2: Substitute the given values

We know \( P_{pencil} = -0.2 \, \text{kg m/s} \) and \( P_{pen} = -0.6 \, \text{kg m/s} \). Substituting these into the formula:
\( P_{total} = -0.2 + (-0.6) \)

Step3: Perform the addition

Adding the two values: \( -0.2 + (-0.6) = -0.8 \, \text{kg m/s} \).

Answer:

The total momentum of the system is \(-0.8 \, \text{kg m/s}\).
