• A.

The particle is continuously going in positive x direction

• B.

The particle is at rest

• C.

The velocity increases up to a time , and then becomes constant

• D.

The particle moves at a constant velocity up to a time , and then stops

• 3.
A person standing near the edge of the top of building throws two balls A and B. The ball A is thrown vertically downward with the same speed. The ball A hits the ground with a speed and the ball b hits the ground with a speed. We have

g downward

• 6.
6 particles A, B, C, D, E, F are located at the vertices of a regular hexagon of side d. All particles move with the same speed v such that the velocity of A is directed towards B, that of B towards C and so on (F is direction towards A). After what time will the particle meet ?
• A.

2d/v

• B.

3d/v

• C.

2d/3v
