A moving object collides with a stationary object. can both objects be stationary after the collision? Explain.

No if the Moving object is very small with respect to stationary object. the moving object moves back with the same speed after striking the staitonary object. and stationary object remains stationary. When a massive body strikes the lighter one.... then their is a certain change in the velocity of the massive moving object and the stationry lighter body will move with the double speed as compare to the incident body and moves forward.

No,because of the momentum conservation. Use the momentum conservation equations you can prove it!!

But momentum isn't always conserved, think perfectly inelastic collisions, when 2 objects stick together. However I don't think they will both remain stationary, thinking about Newton's 3rd law I would say if the initially stationary object is more massive than the moving object then the moving object will have a force exerted on it accelerating it in the opposite direction.
