pcup = +4.5 kg m/s pmug = +2.4 kg m/s what is the total momentum of the system?
pcup = +4.5 kg m/s pmug = +2.4 kg m/s what is the total momentum of the system?
Answer
Explanation:
Step1: Identify the momenta
The momentum of the cup is $P_{cup}=4.5\ kg\cdot m/s$ and the momentum of the mug is $P_{mug}=2.4\ kg\cdot m/s$.
Step2: Calculate total momentum
The total momentum $P_{total}$ of the system is the sum of the individual momenta, so $P_{total}=P_{cup}+P_{mug}$. $P_{total}=4.5 + 2.4=6.9\ kg\cdot m/s$
Answer:
$6.9\ kg\cdot m/s$
