  This article experimentally investigates the exit dynamics of two different
spheres i.e. a smooth sphere and a sphere with dimples at a constant speed.
Employing high-speed experimental observations, the study investigates the key
characteristic lengths and hydrodynamic forces between the sphere's surface and
water. The experiments were performed at different traveling speeds (or Froude
numbers). The results shed light on the drag force coefficient, entrainment
force coefficient, and cross-over force coefficient. In this paper, we have
shown that the surface dimples not only affect the drag force but also the
entrainment force. However, the cross-over force coefficient remains the same.
