The angle between initial directions of an object.

Answer to Problem 43P
The angle between the initial directions is
Explanation of Solution
Given:
The mass of the object 1 is
The mass of object 2 is
The initial velocity of objects is v.
The final velocity of objects is
Formula used:
The expression for law of conservation of momentum is,
Here,
Calculation:
Sketch the motion of objects before and after collision as shown below.
The angle between the objects initial direction by using the relation is,
The angle between the objects initial direction is
The angle between the objects initial direction is,
Conclusion:
Thus, the angle between the objects initial direction is
