The displacement time graph of a moving particle is shown in the figure below. The instantaneous velocity of the particle is negative at the point:

In the following graph, the distance travelled by the body in metres is:

Which one of the following displacement-time graph represents two moving objects \(P\) and \(Q\) with zero relative velocity?

1.		2.
3.		4.

The position (\(x\)) of a particle in a straight line motion is given by \(x = 2 + 10 t - 5 t^{2}~\text{m}\). Its velocity (\(v\)) is best represented by?

1.		2.
3.		4.

The velocity-time graph of a body moving in a straight line is shown in the figure. The displacement and distance travelled by the body in \(6\) seconds are, respectively: 

1. \(8\) m, \(16\) m

2. \(16\) m, \(8\) m

3. \(16\) m, \(16\) m

4. \(8\) m, \(8\) m
