Solve Time to Pull Illinois Jones from Pit

There is also the force of gravity pulling him down. So the net force will be 725 N minus the force of gravity, which is 62kg times 9.8m/s^2. In summary, the minimum time necessary to pull Illinois Jones from the snake pit would be calculated using the equation a=d/t^2 and the given information of F=725 N, m=62 kg, and d=3.9 m. However, the force of gravity also needs to be taken into account, resulting in a lower acceleration and longer minimum time.

Illinois Jones is being pulled from a snake pit with a rope that breaks if the tension in it exceeds 725 N. If Illinois Jones has a mass of 62 kg and the snake pit is 3.9 m deep, what is the minimum time necessary to pull our intrepid explorer from the pit?



F=ma and a=d/t^2



I put in 725 for the force so I had 725=(62kg)(a) and that gave me 11.69 for a, but that doesn't really make sense. That may be right but seems like an insanely high acceleration. Was I wrong in doing that?

The acceleration is produced by the net force. The tension in the rope is not the only force acting on him.
 

1. How long will it take to pull Illinois Jones from the pit?

The time it takes to pull Illinois Jones from the pit will depend on several factors, such as the depth of the pit, the weight of Illinois Jones, and the strength of the team pulling him. It is important to carefully plan and evaluate these factors to determine the estimated time needed to successfully pull him out of the pit.

2. What equipment is needed to pull Illinois Jones from the pit?

The equipment needed to pull Illinois Jones from the pit will also depend on the factors mentioned above. However, some common equipment that may be used include ropes, pulleys, harnesses, and winches. It is important to make sure that the equipment is in good working condition and can handle the weight and force needed to pull Illinois Jones out of the pit.

3. Are there any potential risks or safety concerns when pulling Illinois Jones from the pit?

Yes, there are potential risks and safety concerns when pulling Illinois Jones from the pit. These may include injury to the team pulling him, equipment failure, or further injury to Illinois Jones. It is important to carefully assess and address these risks before attempting to pull him out of the pit.

4. How many people are needed to successfully pull Illinois Jones from the pit?

The number of people needed to pull Illinois Jones from the pit will depend on the weight of Illinois Jones and the strength of the team pulling him. It is important to have an adequate number of people to ensure the safety and success of the rescue operation.

5. What is the best strategy for pulling Illinois Jones from the pit?

The best strategy for pulling Illinois Jones from the pit will depend on the specific circumstances of the situation. It is important to carefully plan and evaluate the factors mentioned above and come up with a safe and effective strategy. This may include using different types of equipment, coordinating with a team, and considering any potential risks or challenges that may arise during the rescue operation.
