Answer:
Explanation:
Let's use the conservation of momentum to solve it.
(1)
- The total initial momentum will be:
- The total final momentum will be:
, but as they stick together after the collision, v1f = v2f = vf.
So we can rewrite (1), using the above information:
Finally, the magnitude of the velocity of the wreckage of the two cars immediately after the collision is:

Answer:
He also formulated his law of Universal Gravitation in the Principia, which states that every point mass attracts every single other point mass by a force pointing along the line intersecting both point.
Explanation:
Answer:
The latent heat of fusion of water is 334.88 Joules per gram of water.
Explanation:
Let the latent heat of ice be 'x' J/g
1) Thus heat absorbed by 100 gram of ice to get converted into water equals
2) heat energy required to raise the temperature of water from 0 to 25 degree Celsius equals
Thus total energy needed equals 
3) Heat energy released by the decrease in the temperature of water from 25 to 11 degree Celsius is
Now by conservation of energy we have
Velocity and speed of a moving body become identical when it tends to move in a straight line.
