Step 1

Mass of disk A and B =0.5 kg

The velocity of A = 6 m/s

The velocity of B = 5 m/s

After collision B travels along a line 30o counterclockwise from the y-axis.

Step 2

When there is not any external force on the body, the momentum of the body remains conserved.

The initial velocity of A along x-direction is VAx1 and final velocity of A along x-direction is VAx2.

The initial velocity of B along x-direction is VBx1 and final velocity of B along x-direction is VBx2.

Apply equation of linear momentum conservation,

Step 3

The initial velocity of A along y-direction is VAy1 and final velocity of A along y-direction is VAy2.

The initial velocity of...
