Final answer:
The student's query pertains to the Physics topic of gravitational potential energy and dynamics, where one needs to calculate the energy and velocity of a bounced ball under the influence of gravity.
Step-by-step explanation:
The student's question is about a golf ball being dropped from a certain height, its subsequent bounce to a lower height, and questions about its potential energy and mass. This scenario is a common problem in Physics, particularly in the study of mechanics involving gravitational potential energy, the conservation of energy, and dynamics of collisions.
To address a similar question, one would typically calculate the gravitational potential energy (mgh) at the initial height, the velocity just before it strikes the ground using the conservation of energy principle, and possibly the efficiency of the bounce represented by the ratio of the rebound height to the initial height. This involves assuming that the only force doing work on the ball is gravity and that energy is conserved in the absence of air resistance and other external forces.
