How do I do this? Part B should already have been explained conceptually.1. Derive an equation for each condition you are asked to determine the effect of doubling the mass on (i.e. velocity and spring compression amount).2. Explain each step of your derivation.3. Explain how your derivation proves the same outcome as your conceptual explanation to this problem.4. Using a derivation show how this apparatus can be used to determine the coefficient of friction between any 2 materials (1 that the box is made of and 1 that the floor of the apparatus is made of).
