Isaac Solis · Answer 1

The type of collision in this system is called inelastic collision where after collision the two objects stick together. We can solve for the final velocity after collision by the expression:

v = m1v1 + m2V2 / (m1+m2)

v = 1 (0.50) + (1) (0) / (1+1) = 0.25 m/s

Therefore, option 3 is the correct answer.
