Question
Observe the image and answer the question below:
What is the momentum of object B before collision?
What is the momentum of object B before collision?
- 2050 m/s
- 1800 m/s
- 3200 m/s
- 650 m/s
Hint:
Use linear momentum formula i.e. momentum is product of mass and velocity.
The correct answer is: 3200 m/s
Momentum of object B before collision will be product of its mass and velocity i.e. 80*40=3600m/s.
