A stick is thrown in the air and lands on the ground at some distance from the thrower. The centre of mass of the stick will move along a parabolic path

  • A. in all cases
  • B. only if the stick is uniform
  • C. only if the stick has linear motion but no rotational motion
  • D. only if the stick has a shape such that its centre of

Step-by-step solution

The center of mass of any object under the influence of gravity alone (ignoring air resistance) follows a parabolic trajectory, regardless of its shape, mass distribution, or rotational motion. This is because the motion of the center of mass is determined solely by external forces, and gravity is the only external force acting on the stick during its flight.
