Direction: Read the passage carefully and answer the following question.An object of mass 1.5 kg travelling in a straight line with a velocity of \[5\text{ }m\text{ }{{s}^{-1}}\] collides with a wooden block of mass 5 kg resting on the floor.This object sticks with wooden block after collision and both move together in a straight line.The total momentum after collision is

• A. \[3.5\text{ }kg\text{ }m\text{ }{{s}^{-1}}\]
• B. \[1.5\text{ }kg\text{ }m\text{ }{{s}^{-1}}\]
• C. \[7.5\text{ }kg\text{ }m\text{ }{{s}^{-1}}\]
• D. \[2\text{ }kg\text{ }m\text{ }{{s}^{-1}}\]
