Physics
A white billiard ball with mass mw = 1.5 kg is movingdirectly to the right with a speed of v = 3 m/s and collideselastically with a black billiard ball with the same massmb = 1.5 kg that is initially at rest. The two collideelastically and the white ball ends up moving at an angle above thehorizontal of θw = 30° and the black ball ends up movingat an angle below the horizontal of θb = 60°.

Answer & Explanation Solved by verified expert
Let the velocity of white ball is v(w) and velocity of black ball is v(b).
Apply the law of momentum conservation in X-axis:-
( 1.5 kg ). ( 3 m/s ) + 0 = ( 1.5 kg ) .v(w) . cos30* + (1.5 kg ).  v(b) . cos 60*
Simplify the equation
1.299 v(w ) + 0.75 v(b) = 4.5 ............... (1)
Along y- axis, the momentum conservation yields
( 1.5 kg ) . v(w) . sin30* = ( 1.5 kg ) . v(b) . sin60*
v(w) = 1.732 v(b) ........... (2)
Substitute (2) in equation (1)
1.299
