The new velocity of the
Answer to Problem 77A
Explanation of Solution
Given:
The mass of the 1st ball,
The mass of the 2nd ball,
Initial velocity of 1st ball,
Initial velocity of 2nd ball,
After colliding, the new velocity of the 2nd ball,
Formula used:
Momentum of an object of mass m and moving with velocity v is given by,
And, law of conservation of linear momentum: Momentum is conserved in a closed and isolated system and is given by,
Calculation:
Consider both the balls as a system, then it will be a closed and isolated system and law of conservation of momentum can be applied to it.
Let, the final speed of the
Using given values in above,
Conclusion:
Thus, the new velocity of the
