A meter stick is placed vertically at the origin on a frictionles surface. A gentle push in +x direction is given to the top most point of the rod. When it has fallen completely x-coordinate of center of rod is at

A rod length L is held vertically on a smooth horizontal surface. The top end of the rod is given a gentle push. At a certain instant of time, when the rod makes an angle theta with horizontal the velocity of COM of the rod is v_(0) . The velocity of the end of the rod in contact with the surface at that instant is:

Four particles, each of mass 1kg, are placed at the corners of a square of side one meter in the X - Y plane. If the point of intersection of the diagonals of the square is taken as the origin, the coordinates of the centre of mass are

A uniform rod of mass m, length l is placed over a smooth horizontal surface along y -axis and is at rest as shown in figure. An impulsive force F is applied for a small time Deltat along x-direction at point A. The x-coordinte of end A of the rod when the rod becomes parallel to x-axis for the first is (in itially the coordinates opf centre of mass of the rod is (0,0).

A rod of mass M and length L is lying on a horizontal frictionless surface. A particle of mass 'm' travelling along the surface hits at one end of the rod with a velocity 'u' in a direction perpendicular to the rod. The collision is completely elastic. After collision, particle comes to rest. The ratio of masses ((m)/(M))" is "(1)/(x) . The value of 'x' will be_____.

A uniform rod of mass m and length l is placed over a smooth horizontal surface along the y -axis and is at rest as shown in Fig. An impulsive force F is applied for a small time /_\t along x -direction at point A . The x -coordinate of end A of the rod when the rod becomes parallel to x -axis for the first time is [initially, the coordinate of centre of mass of the rod is (0, 0) ]
