Final answer:
The question from Physics involves kinematics and requires the understanding of deceleration to predict how much more distance a bullet will penetrate into a target after already losing half its velocity. The additional distance can be found using kinematic equations, but exact values cannot be provided without more specific information about velocity and deceleration.
Step-by-step explanation:
The question involves the concept of deceleration and kinematics in Physics. When a bullet is fired into a target and loses half its velocity after penetrating 15 cm, we can infer that the bullet will continue to decelerate until it comes to rest. Since the loss of velocity is likely due to a constant decelerating force, we can use the kinematic equations for uniformly accelerated motion, with acceleration here in the context of deceleration.
As the bullet has lost half its velocity over 15 cm, it continues with that reduced velocity for the remaining distance until it stops. With constant deceleration, the distance it can penetrate further until it comes to rest, represented as d, can be found using the equations of motion: d = v2 / (2a), where v is the final velocity (which is half the initial velocity in this case) and a is the deceleration. However, actually solving this problem would require additional specifics like the initial velocity and the deceleration value.
Without these details, we're unable to provide numerical answers but can assert that the same principles of kinematics would apply to determine the remaining distance the bullet would penetrate before coming to rest.
