+ | 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. (Thundercloud Neutralizing Drone). | ||

+ | 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. | ||

The track is not built to contain the T.N.D. at very high speeds; the maximum speed it should reach before hitting the spring is $v_{max} = 50$ m/s. |
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 crazy 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.
