A flat rigid body is moving in x – y plane on a table. The plane of the body lies in the x – y plane. At an instant it was found that some of the velocity components of its three particles A, B and C were V_(Ax) = 4 m//s, V_(Bx) = 3 m//s and V_(cy) = - 2 m//s, respectively. At the instant the three particles A, B and C were located at (0,0) (3,4) , (4,3) (all in meter ) respectively in a co-ordinate system attached to the table.
