Acceleration of particle moving in straight line can be written as `a=(dv)/(dt)=v(dv)/(dx)`. From the given graph find acceleration at `x=20 m`.

Let v and a be the instantaneous velocity and acceleration of a particle moving in a plane. Then rate of change of speed (dv)/(dt) of the particle is equal to

Let v and a be the instantaneous velocity and acceleration of a particle moving in a plane. Then rate of change of speed (dv)/(dt) of the particle is equal to

(A): Plotting the acceleration-time graph from a given position time graph a particle moving along a straight line is possible. (R): From position time graph sign of acceleration can not be determined.

For a particle moving in straight line with increasing speed the sppropriate sign of acceleration a and velocity v can be:

For a particle moving in straight line with increasing speed the appropriate sign of acceleration a and velocity v can be:
