The velocity-displacement graph of a particle is shown in the figure.
The acceleration-displacement graph of the same particle is represented by :
The acceleration-time graph for a body is shown in the graph. Which of the following graphs would probably represent velocity of the body plotted against time:-
A Body moves $6\, m$ north. $8 \,m$ east and $10\;m$ vertically upwards, what is its resultant displacement from initial position
For the velocity-time graph shown in the figure, in a time interval from $t=0$ to $t=6\,s$, match the following columns.
Colum $I$ | Colum $II$ |
$(A)$ Change in velocity | $(p)$ $-5 / 3\,Sl$ unit |
$(B)$ Average acceleration | $(q)$ $-20\,SI$ unit |
$(C)$ Total displacement | $(r)$ $-10\,SI$ unit |
$(D)$ Acceleration at $t=3\,s$ | $(s)$ $-5\,SI$ unit |
$Assertion$ : A body can have acceleration even if its velocity is zero at a given instant of time.
$Reason$ : A body is numerically at rest when it reverses its direction.
