Answer» Concave mirror Convex mirror Biconcave mirror Biconvex mirror Solution :`"Area of OAF"=(1)/(2)xx2xx4=4` `"Area of ABG F"=2xx4=8` `"Area of BGHC"=(1)/(2)(4+2.5)xx0.5=1.625` `"Area of CDEH"=2xx2.5=5` `"Total area under F - t graph = Change in momentum"` `RARR m(V-u)=18.625` `rArr v=(18.625)/(2)+5=14.25ms^(-1)`
