Question

Of the following sets of displacements the one which will be capable of returning a car to its starting point\

Professor PC Thomas Classes · Answer

If three displacements take a body back to the starting point, they must form a triangle\ In any triangle, the sum of two sides must be greater than the third side\ If four displacements take a body back to the starting point, they must forma quadrilateral. In any quadrilateral the sum of three sides must be greater than the fourth side.\ Look for the set which satisfies this condition\
