Center of MassMedium
Question
A ball moves in a closed box making several collisions with the walls. The box is kept on a smooth surface. The velocity of the centre of mass during the motion of the ball.
Options
A.of the box remains constant
B.of the box plus the ball system remains constant
C.depends on value of e
D.of the ball relative to the box remains constant
Solution
Since no external force acting on system hence VCM remain constant.
