Question
A 0.13kg mass is placed on a very stiff spring that extendsvertically 3cm from the floor. A person compresses the springby pushing down on the mass. As a result the bottom of themass is now 1 cm above the floor. If the spring constant is2350N/m a) Determine the maximum height above the floor that the lowersurface of the mass will reach once it is released and subsequentlylaunched as the spring uncoils. Ignore drag and/or otherfrictional forces. b) Determine the kinetic energy of the mass when its lowersurface is 20cm above the floor. c) How much work did the person have to do to compress thespring? How is your answer here related to your answer inpart a? Explain your reasoning. A 0.13kg mass is placed on a very stiff spring that extendsvertically 3cm from the floor.
