#### The graph of displacement-time for a body travelling in a straight line is given. We can conclude that

Physics-General

- The velocity is constant
- The velocity increases uniformly.
- The body is subjected to acceleration from to .
- The velocity of the body at is zero.

#### Answer:The correct answer is: The velocity of the body at is zero.At the point , the tangent to the curve is parallel to time axis. So, velocity at is zero. But acceleration is not zero. Note that the displacement corresponding to the point is not zero.

#### Figure shows the acceleration-time graphs of a particle. Which of the following represents the corresponding velocity-time graphs?

Since acceleration is constant, therefore there is uniform increase in velocity. So, the graph is a straight line slopping upward to the right. When acceleration becomes zero, velocity is constant. So graph is a straight line parallel to the time-axis.
