2.2 Mary-go-round of mass 300kg and 3m radius with moment of inertia - MR² is subject to friction torque 50Nm. A child of 25kg is sitting at distance 2m from the center of the axis of rotation. Initially, mary-go-round is at rest, at t=0s parent applies force of 50N which gives the maximum toque to marry- go-round for 10s. Answer the following questions. a) (3 points) What is the total moment of inertia? (Marry-go-round and a child.) b) (3 points) What is the magnitude of maximum toque? c) (3 points) What is the angular momentum at t=2s?

Responses should be as simple as possible, and in typed form, with all applicable units, following a clear and straightforward logical structure. NO hand-drawn explanations are allowed. Ensure the appropriate use of significant figures, and when applicable, employ the "variable space" framework for providing answers.

Suppose a Cobb-Douglas Production function is given by the following: P(L, K) = 20L0.5 K0.5 where I is units of labor, K is units of capital, and P(L, K) is total units that can be produced with this labor/capital combination. Suppose each unit of labor costs $400 and each unit of capital costs $3,200. Further suppose a total of $192,000 is available to be invested in labor and capital (combined). A) How many units of labor and capital should be "purchased" to maximize production subject to your budgetary constraint? Units of labor, L = Units of capital, K = B) What is the maximum number of units of production under the given budgetary conditions? (Round your answer to the nearest whole unit.)

Using the tables for Densities of Inorganic and Organic Liquids (mol/dm3) of Perrys' Chemical Handbook. What is the density of water, in kg/m3, at 308.3 K? Recall that there are two available equations for the density of water different from the equation used for all other compounds in the table; use the equation with a smaller range (the simpler equation, in terms of T).
