Question
The graph between the displacement
and
for a particle moving in a straight line is shown in figure. During the interval
and
the acceleration of the particle is

, 
- + 0 + +
- - 0 + 0
- + 0 - +
- - 0 - 0
The correct answer is: - 0 + 0
Region
shows that graph bending toward time axis
acceleration is negative.
Region
shows that graph is parallel to time axis
velocity is zero. Hence acceleration is zero.
Region
shows that graph is bending towards displacement axis
acceleration is positive.
Region
shows that graph having constant slope
velocity is constant. Hence acceleration is zero
