pcar = -1,200 kg m/s pbike = +150 kg m/s what is the total momentum of the system?
pcar = -1,200 kg m/s pbike = +150 kg m/s what is the total momentum of the system?
Answer
Explanation:
Step1: Identify the momenta
The momentum of the car $P_{car}=- 1200\ \text{kg m/s}$ and the momentum of the bike $P_{bike}=150\ \text{kg m/s}$.
Step2: Calculate total momentum
The total momentum $P_{total}$ of the system is the sum of the momenta of the car and the bike. So $P_{total}=P_{car}+P_{bike}$. $P_{total}=-1200 + 150=-1050\ \text{kg m/s}$
Answer:
$-1050\ \text{kg m/s}$
