A submarine is currently being developed to take tourists on sightseeing trips to tropical coral reefs. According to engineering guidelines the sub must be able to withstand a pressure of 10.09 N per square millimeter.
Required:
a. To what depth can the submarine safely descend in seawater?
b. If the submarine is used in freshwater instead, is its maximum safe depth greater than, less than, or the same as the seawater? Explain

Aspring is used to stop a 50-kg package which is moving down a 20º 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.
