Work, Power and Energy Test POSSIBLE POINTS: 2 Base your answer to the next 2 questions on the information below and on your knowledge of physics. A toy launcher that is used to launch small plastic spheres horizontally contains a spring with a spring constant of 50. newtons per meter. The spring is compressed a distance of 0.10 meter when the launcher is ready to launch a plastic sphere. [Show all work, including the equation and substitution with units.] 1) Determine the elastic potential energy stored in the spring when the launcher is ready to launch a plastic sphere. [Neglect friction.] 2) The spring is released and a 0.10-kilogram plastic sphere is fired from the launcher. Calculate the maximum speed with which the plastic sphere will be launched
