pcar = -2,000 kg m/s pbus = +5,000 kg m/s what is the total momentum of the system?
pcar = -2,000 kg m/s pbus = +5,000 kg m/s what is the total momentum of the system?
Answer
Explanation:
Step1: Identify the momenta
The momentum of the car is $P_{car}=- 2000\ kg\cdot m/s$ and the momentum of the bus is $P_{bus}=+5000\ kg\cdot m/s$.
Step2: Calculate total momentum
The total momentum $P_{total}$ of the system is the sum of the momenta of the car and the bus. So $P_{total}=P_{car}+P_{bus}$. Substitute the values: $P_{total}=-2000 + 5000$. $P_{total}=3000\ kg\cdot m/s$.
Answer:
$3000\ kg\cdot m/s$
