Question

p_{tire1} = -135 kg m/s p_{tire2} = +200 kg m/s
what is the total momentum of the system?

Explanation:

Step1: Sum the two momentum values

$P_{total} = P_{tire1} + P_{tire2}$

Step2: Substitute given values

$P_{total} = -135\ \text{kg m/s} + 200\ \text{kg m/s}$

Step3: Calculate the total momentum

$P_{total} = 65\ \text{kg m/s}$

Answer:

$65\ \text{kg m/s}$
