Will the acceleration increase or decrease with increase in velocity ?
The position$(x)$ of a particle at any time$(t)$ is given by $x(t) = 4t^3 -3t^2 + 2$ The acceleration and velocity of the particle at any time $t = 2\, sec$ are respectively
The acceleration of a train between two stations is shown in the figure. The maximum speed of the train is $............\,m/s$
Colum $I$ | Colum $II$ |
$(A)$ Distance travelled in $3\,s$ | $(p)$ $-20$ units |
$(B)$ Displacement in $1\,s$ | $(q)$ $15$ units |
$(C)$ Initial acceleration | $(r)$ $25$ units |
$(D)$ Velocity at $4\,s$ | $(s)$ $-10$ units |
The velocity-time and acceleration-time graphs of a particle are given as Its position-time graph may be gvien as
