Answer» ement=final position-initital positionLet's the starting point be OFrom O he is going at point A in SOUTH whose distance from O is 12 mFrom A he is going at point B in WEST whose distance from A is 35mIf we JOIN all THREE points together we got a right angle triangle OAB.WHOSE OA=12m=aAB=35M=baccording to pithagoras theoramBO=UNDERROOT(a^2+b^2)=underroot(12^2+35^2)=underroot(144+1225)=underroot(1369)=underroot(37×37)=+-37since displacement CANT be negative so the answer will be 37m |
