Answer :
Final answer:
Without information on the type of collision, we cannot determine the kinetic energy after impact; therefore, the answer is 'Insufficient information provided'. Therefore, Option d is correct.
Explanation:
Option d is correct. The question addresses the concept of conservation of energy during a collision, which is a topic in physics. If an object starts with a potential energy (PE) of 1.57 and has a kinetic energy (KE) before impact of 1.57, without additional information about the type of collision (elastic or inelastic), we cannot definitively determine the KE after impact. This is because during an inelastic collision, some kinetic energy is converted into other forms of energy, such as heat or sound, and thus the KE after the collision would be less than before. During an elastic collision, kinetic energy is conserved, so the KE would be the same before and after. Since we do not have information about the type of collision or if any external forces are doing work, the best answer from the given choices is d) Insufficient information provided.
