( x=t^{2}-2 t ) ( v=2 t-2 quad ) (dir nanges after I secood) I Displace ment ( =x(2)-operatorname{tg}(0) ) ( =(4-4)-(0) ) ( =0 m ) (2) ( frac{text { Distance }}{frac{1}{4^{n}}}=frac{2 *(x(1))}{2 m} ) (3) Au. Helocity = Displaument ( =frac{0}{2}=0 mathrm{ms}^{-1} ) (4) Averagespeed ( =frac{text { Distanu }}{operatorname{tim} e}=frac{2}{2}=operatorname{lm} s^{-1} )
