Final answer:
The correct man overboard procedure is to immediately stop the vessel and initiate rescue operations. In a physics-related scenario, the height from which a life preserver is dropped can be calculated using kinematics equations, considering the initial velocity, time to impact, and gravity.
Step-by-step explanation:
When someone falls overboard from a vessel, time is of the essence. The correct procedure is to immediately stop the vessel and initiate rescue procedures, not to continue sailing or wait for assistance. As for providing first aid, this is crucial once the person has been brought back onto the vessel or to stable ground. At that point, administering first aid and, if necessary, cardiopulmonary resuscitation (CPR) is essential to address any injuries or health issues.
Physics Problem
In relation to the physics problem, the knowns are:
-
- Initial velocity (v0) of the life preserver: 1.40 m/s
-
- Time (t) it takes to reach the water: 1.8 s
-
- Acceleration due to gravity (g): 9.8 m/s2
To find the height (h) from which the preserver was released, we can use the equation:
h = v
0
t + 1/2gt
2
Plugging in the known values, we get:
h = (1.40 m/s)(1.8 s) + 1/2(9.8 m/s2)(1.8 s)2
After calculation, the height is found to be approximately 17.64 meters above the water.
Rescue Protocols
Rescue personnel needs to be prepared with equipment like fire-resistant clothing and breathing apparatus when entering hazardous environments such as burning buildings or accident sites. They are also trained to efficiently search and rescue victims and to administer necessary life-saving procedures like first aid.
