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?

Kinesiologists—scientists who study human motion—can measure the forces that act on runners as they round a curve. The forces on a runner’s feet are a vertical normal force that, on average, serves to counteract gravity, and a static friction force parallel to the ground and pointing toward the center of the runner’s circular path. The average value of this inward-pointing force is measured to be 600 N for a 75 kg runner rounding a curve that has a 2.5 m radius. What is this runner’s speed?
For this problem, we want to estimate the answer, so our assumptions may be a little unrealistic. Suppose we want to estimate how much air we need to send to a space station, assuming we cannot recycle air. Suppose four astronauts are in a spherical space station. If each of them typically breathes about 500 cm³of air with each breathe, and take 15 breathes per minute (average resting value): a. What is the volume of air you would need in the space station if these four astronauts stayed for a full year? b. If the density of air is 1.25 kg/m³ and it costs (thanks to SpaceX) a mere $100/kg to send objects to the space station, how much money would the astronaut air supply cost?
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.)

A car is traveling at 22.0 m/s when the driver suddenly applies the brakes, giving the car a constant deceleration. The car comes to a stop in a distance of 120.0 m. How fast was the car moving when it was 30.0 m past the point where the brakes were applied? O 23.5 m/s 15.0 m/s 7.50 m/s 19.1 m/s 28.0 m/s
