Question

pball1 = +2.0 kg m/s pball2 = -5.8 kg m/s
what is the total momentum of the system?

Explanation:

Step1: Define total momentum

Total momentum is the sum of individual momenta: $P_{total} = P_{ball1} + P_{ball2}$

Step2: Substitute given values

$P_{total} = 2.0\ \text{kg m/s} + (-5.8\ \text{kg m/s})$

Step3: Calculate the sum

$P_{total} = 2.0 - 5.8 = -3.8\ \text{kg m/s}$

Answer:

$-3.8\ \text{kg m/s}$
