Two objects of masses 100 g and 200 g are moving along the same line and direction with velocities of 2 m/s and 1 m/s, respectively. They collide and after the collision , the first object moves at a velocity of 1.67 m /s Determine the velocity of the second object.

Two objects of masses 100 g and 200 g are moving along the same line and direction with velocities of 2ms^(-1) and 1ms^(-1) respectively. They collide and after the collision, the first object moves with a velocity of 1.67ms^(-1) Determine the velocity of the second object.

Two objects, each of mass 1.5 kg, are moving in the same straight line but in the opposite directions. The velocity of each object is 2.5 ms^(-1) before the collision during which they stick together. What will be the velocity of combined object after collision ?
