NASA has processed most of the data but is looking for help in identifying two of the remaining elements from the samples. They know that both elements are main group elements belonging in either Group 2 or Group 18. Group 2 elements are highly reactive, while Group 18 elements are unreactive. Group 2 elements are also solid at room temperature, while Group 18 elements are gases at room temperature.

Aspring is used to stop a 50-kg package which is moving down a 20ΒΊ incline. the spring has a constant k = 30 kn/m and is held by cables so that it is initially compressed 50 mm. knowing that the velocity of the package is 2 m/s when it is 8 m from the spring and neglecting friction, determine the maximum additional deformation of the spring in bringing the package to rest.
