Question

derive all kinematic equations using graphical method

Answer 1

A = v-u/tV-u=atV=u+at......(1)X= area of DEC + area of OBCE = 1/2 × CE× DC× CE× AE = 1/2 (t)(at)+ t×u =1/2 at^2 ut S= 1/2 at^2+ut.....(2)X= area of ABDEAx = 1/2 (AE+BD)(EC)X=1/2 (U+V)ECa= v-u/ta=v-u/ECEC=V-U/aX=1/2 (U+V)(V-U)/a2ax= v^2-u^2V^2=U^2+2ax...... (3)
