The position of a particle moving along the x-axis at certain times is given below :
 

t (s)	0	1	2	3
x (m)	–2	0	6	16

Which of the following describes the motion correctly 
 

  


$$\begin{gathered} from the given data , ins\tan t velocity is estimated u\sin g two successive readings to evaluate the consistency \\ Ins\mathrm{tantan}eous velocity v=\frac{\Delta x}{\Delta t} \\ By u\sin g the data from the table \\ {v}_1=\frac{0-(-2)}{1}=2m/s. \\ {v}_2=\frac{6-0}{1}=6m/s \\ {v}_3=\frac{16-6}{1}=10m/s \\ hence motion is non-uniform but accelerated \end{gathered}$$
