Question
The graph of displacement-time for a body travelling in a straight line is given. We can conclude that - The velocity is constant
- The velocity increases uniformly.
- The body is subjected to acceleration from to .
- The velocity of the body at is zero.
- The velocity is constant
- The velocity increases uniformly.
- The body is subjected to acceleration from to .
- The velocity of the body at is zero.
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.
