CBSE Class 9 - Conservation of Linear Momentum Videos
- A boy of mass 45 kg running 6 m/s jumps onto a 30 kg trolley moving in the same direction at 1.5 m/s. Their common velocity will be: A. 4.0 m/s B. 4.2 m/s C. 6.5 m/s D. 8.3 m/
- what is linear momentum ?
- a bullet of mass 20 grams is horizontally fired with a volicity of 150 mls from pistal of mass 2 kg what is the recoil volicity of pistal
- Two hockey players of opposite teams, while trying to hit a hockey ball on the ground collide and immediately become entangled. One has a mass of 60 kg and was moving with a velocity 5.0 m s–1 while the other has a mass of 55 kg and was moving faster with a velocity 6.0 m s–1 towards the first player. In which direction and with what velocity will they move after they become entangled? Assume that the frictional force acting between the feet of the two players and ground is negligible.

- The mass of a cannon is 500 kg. From this cannon a bullet of 10 kg mass was thrown at a speed of 20 m / s. How long does a cannon retreat if the resistance of the land is one tenth the weight of the cannon?
