The green d struck by the orange disk moving initially to the right at Voi-4.65 m/s as in Figure (a) shown below. After the colision, the orange disk moves in a direction that makes an angle of after the collision. 38.00 with the horizontal axis while the green disk makes an angle of 52.00 with this axis as in figure (b). Determine the speed of each disk 2.95 your response differs from the correct answer by more t 2.31 Your response differs from the correct answer by more than 10%.

The sum of their vertical momenta is zero:
1) Vo*sin38° = Vg*sin52°
=> Vo*0.616 - Vg*0.788 = 0
The sum of their horizontal momenta must equal the initial momentum of orange:
2) Vo*cos38° + Vg*cos52° = 4.65
Vo*0.788 + Vg*0.616 = 4.65
In each case, since the masses are equal, they cancel out.
Solving (1) & (2) simultaneously,
Vo = 3.66 m/s
Vg = 2.86 m/s
