Handwrite your work and submit all three FRQ answers together to the Unit 4 Exam FRQ Canvas Assignment. A 50 kg disk is spinning about a vertical axis of rotation with a radius of 2.3 m and a rotational inertia of 0.15 mr2 and it has an initial angular velocity of 40 rad/s. A 10 kg mass falls on to the disk and sticks to it at 0.6 m away from the axis of rotation. The rotational inertia of the mass is mr2. Calculate the angular velocity of the disk-mass system after the collision.

Can you please answer the first two parts

A 60kg kid is on a roller coaster that travels at a constant 8m/s around several features that each have a radius of 6m. For each of the situations, draw a qualitatively accurate force diagram (indicating balanced or unbalanced) for the kid. Determine the force on the kid from his seat for each. State all equations and show your work.

Please Answer the following question step-wise with detailed explanations. Thanks in advance? ❤️

LEARN MORE REMARKS Only simple geometries-rectangles and triangles-can be solved exactly with this method. More complex shapes require calculus or the square-counting technique in the next worked example. QUESTION When stretching springs, does half the displacement require half as much work? (Select all that apply.) Yes, because the work is equal to the force times the distance. Yes, because the spring exerts a constant force. Yes, because half the displacement means the force from the spring is half as large. No, because the spring does not exert a constant force. No, because the force of the spring is proportional to x. No, because the force exerted by the spring is proportional to x². PRACTICE IT Use the worked example above to help you solve this problem. One end of a horizontal spring (k = 87.4 N/m) is held fixed while an external force is applied to the free end, stretching it slowly from XA = 0 to xB = 4.69 cm. (a) Find the work done by the applied force on the spring. J (b)…
