Question

Marble A is placed in a hollow tube, and the tube is swung in a horizontal plane causing the marble to be thrown out. As viewed from the top, which of the following choices best describes the path of the marble after leaving the tube?

Answer 1

Answer:

The direction of ball will be Number 4 (as can be seen in attached picture) ---- the path of ball will be making some angle when it leaves the tube.

Explanation:

The question is incomplete. So the picture, which is missing in question, is attached for your review.

As it can be seen in the picture, the ball coming out of the tube will have two components of velocity. One is along the length of tube (because ball is moving in that direction and is coming out from the hole), other is velocity component will be perpendicular to the tube (because the ball is made to move in that direction as the tube is rolling on the surface).

So, taking the resultant of two vectors of velocity, the resultant direction of ball will be Number 4 (as can be seen in attached picture) ---- the path of ball will be making some angle when it leaves the tube.

Answer 2

The path of the marble will be as depicted in number 4 of the attached image.

What will the path of the marble go in a straight line?

The particle velocity of the marble when it leaves the tube will have two components for factors that can be resolved in two directions.

The first is that it will go along a path that is parallel to that of the tube, then the other will run perpendicularly to the tube.

These two components will create a straight line with an angle that is vertical or horizontal.
