Two balls slide over a frictionless horizontal surface from opposite direction

as shown in Figure Q2(b). The first object with mass m1=5 kg is propelled

with initial speed v10 = 4.5 m/s towards the second object of mass m2 = 2.5

kg, which is moving with speed v20 = 6.0 m/s. After the collision, object m1

have velocity v1f = 3.0 m/s directed at θ1 = 30°.

calculate the velocity and angle of deviation of object 2
