Centre of mass of a body is the point where we can assume its entire mass is concentrated. To find Centre of mass of the given sysytem of four particles, first we identify the coordinates of their positions. M1 = 1kg M2 = 2kg M3 = 3kg M4= 4kg Let 1kg mass be at the origin. ( X1, y1 ) = (0,0) (X2,...

( X1, y1 ) = (0,0) (X2, y2) = (1,0) (X3, y3 ) = (1,1) (X4,y4) = (0,1) Now using the formula Xcm = (m1x1 + m2x2 + m3x3 + m4x4)/ (m1+m2+m3+m4) We can find the centre of mass Xcm = (0+2+3+0)/(1+2+3+4) = (1/2)m Ycm = (0+0+3+4)/(1+2+3+4) = (7/10) m read less

Is it possible, the displacement can be greater than the distance travelled by an object?
No, aa for euclidean space, the displacement is always greater than or equal to the distance travelled as goes by it's definition that it is the shortes way possible to reach from point A to point B. And...
