-After your team gave such accurate advice regarding the safety of the monitoring equipment on top of FTOE, the local S.P.A.R.T.A.N. station chief has asked you to assist with a top secret project.  This time, in an effort to prevent future storms, you are tasked with overseeing the design and launch of an experimental government device know as a T.N.D. (Thundercloud Neutralizing Drone).  She says she can't tell you why the drone was developed or how it works, but it needs to remain stationary in the center of a storm cloud, where it can be remotely triggered to neutralize the charges in the cloud and stop the storm.  The T.N.D. is spherical with a radius of $r_{TND} = 2$ m, and has a mass of $m_{TND} = 500$ kg. It has a small propulsion system that can be turned on remotely to allow it to maintain its altitude, but the propulsion system isn't powerful enough to launch the drone.  +After your team gave such accurate advice regarding the safety of the monitoring equipment on top of FTOE, the local S.P.A.R.T.A.N. station chief has asked you to assist with one of the top secret projects underway at the lab.  This time, in an effort to prevent future storms, you are tasked with overseeing the design and launch of an experimental government device know as a T.N.D.

-In order to deploy the T.N.D., it must be launched upward via a massive spring to the proper height in the atmosphere.  Once at thundercloud height, its propulsion system will hold it in place while it neutralizes the cloud.  You are tasked with carrying out the crucial step BEFORE the launch can happen: compressing the **locking** spring that will be used in the launch. The mechanism for how the spring is compressed is depicted in the output below:+In order to deploy the T.N.D., it must be driven by truck to the storm and launched upward via a massive spring to the proper height in the atmosphere.  Once at thundercloud height, its propulsion system will hold it in place while it neutralizes the cloud.  You are tasked with carrying out the crucial step BEFORE the launch can happen: compressing the **locking** truck-mounted spring that will be used in the launch.

 2. The spring is very large. In order for the compressed spring-T.N.D. system to fit on a transport truck, the spring must be compressed at least $\Delta x_{min} = 6$ m in length. 2.

-You must determine a range of charge that would be acceptable to place on the T.N.D., such that the compression process is both safe AND effective. Once compressed, the spring-T.N.D. system can be transported by truck to any desired launch location, where the T.N.D. can be remotely launched by the spring into the atmosphere to hopefully mitigate some of the destructive weather in Lakeview.+You must determine a range of charge that would be acceptable to place on the T.N.D., such that the compression process is both safe AND effective.
