The speed and direction of each ball after the collision.
Answer to Problem 22P
The speed of first ball after the collision
The speed of second ball after the collision
Explanation of Solution
Given:
The mass of first ball is
The initial velocity of the first ball is
The mass of second ball is
The initial velocity of the second ball is
Formula used:
The expression for relative velocity is,
Here,
The expression for law of conservation of momentum is,
Here,
Calculation:
The velocity of first ball after collision is,
The speed of ball using the relation of conservation of momentum is,
The velocity of second ball after collision is
The speed of first ball after the collision using equation (1) as follows:
Conclusion:
Thus, the speed of first ball after the collision
Thus, the speed of second ball after the collision
