4) The figure below shows the path of a ball leaving the ground at point X and about to hit the ground at point Z.

If air resistance is negligible, the vertical component of

velocity is maximum at Y.

acceleration is the same at Y as at Z.

velocity is the same at X and Z.

displacement is minimum at Y.
