Given information

is the Mass of ball A. 

is the Mass of ball B. 

Along the x-axis, The initial velocity of ball A =

is the initial velocity of ball B.   

is the angle of deflection of ball A. 

is the final speed of ball A.

 

The equations of conservation of momentum along the x-axis and y-axis are very useful in analyzing two-dimensional collisions of particles, where one is originally stationary (a common laboratory situation). But two equations can only be used to find two unknowns, and so other data may be necessary when collision experiments are used to explore nature at the subatomic level.

Step-by-step explanation

Step 1.

From part (a), we observed equations of conservation of momentum along x and y-axis

x-axis-     

y-axis-
