AP Physics C | Secret Agent Abandoned Factory Infiltration Background Report Collected Data: (4 points) Hello Create a data table to show all of the quantities that you gathered in this process. We have just learned from a reliable source that terrorists are *Insert Table* 30 points preparing a plan, the exact nature of which eludes us for the In this lab report, you will be submitting your final report as a secret agent to explain the success of your moment, that will allow them to enter an old abandoned factory. mission and how you got through the fan. This isolated factory is being closely watched by the terrorists and it is very dangerous to approach it. The spy we sent to the In completing this report you will address the following objectives: location was able to reveal a few pieces of crucial information Calculate the torque acting on a rigid body due to the gravitational force. that we are passing on to you here. We recently lost contact with Calculate unknown magnitudes and directions of forces acting on an extended rigid body that is in a Demonstrated Calculations: (15 points) the spy and we fear the worst. state of translational and rotational equilibrium. . Calculate the moment of inertia of point masses that are located in a plane about an axis perpendicular Your mission, if you accept it, is to secretly enter the factory to get information about the terrorists' activities. The factory is located Show clear calculations for each of the following: to the plane. at the bottom of a cliff. As you can see in this photo, there is a radar antenna at the top of the cliff. Our spy told us that this antenna 1. Calculate the moment of inertia of the rotating object in this problem (round answers to tenths place). . Calculate unknown quantities such as angular positions, displacement, angular speeds, or angular is non-functional and that it can therefore rotate freely about its axis. Our plan for entering the factory is to descend from the cliff to acceleration of a rigid body in uniformly accelerated motion, given initial conditions. an air duct on the roof. It will be impossible for you to put your feet directly on the factory roof, because your presence might be . Calculate unknown quantities such as net torque, angular acceleration, or moment of inertia for a rigid detected. You will therefore have to descend directly body undergoing rotational acceleration. into the air duct, which is equipped with a fan that 2. Draw a free-body diagram for each of the moving objects in this problem. turns slowly enough to give you just enough time to pass through. Your descent will have to be Three Step Cycle Table: (10 points) synchronized with the rotation of the fan blades, so Antenna Include your final version of the Three Step Cycle Table. that you arrive at the duct when the passage is open. 3. What is the force responsible for the radar antenna's rotational movement? For an inconspicuous, predictable and gentle descent, What We Know To Determine Summary we suggest that you wind a cable around the radar antenna. Then, with you hanging from the cable, it 4. Determine the basic formula that describes the dynamics of a body's rotational movement. m1 = 178.6 kg should unwind, dragging the antenna in a rotational mz = 180.7 kg motion and allowing you to descend into the factory. ma = 573.4 kg A diagram of the plan is provided on the next page m4 = 89.0 kg You can see that this mission is very dangerous. To 5. Calculate the secret agent's descent time from the top of the cliff to the factory (round your answer to ms = 77.1 kg maximize your chances of success and ensure you do the tenths place). L3 = 41.5 m hot compromise your safety, we first want to conduct L4 = 34.5 m a simulation on a reduced scale. You will be able to take part in the operation only if you pass this test. n1 = 3.73 m You will be given a model of the setup. You will have 12 = 3.73 m to determine when to time the descent so the secret 13 = 0.92 m agent can enter the factory without touching the fan Conclusions: (1 point) 14 = 0.33 m blade in the air duct. Test your calculations in the simulation provided in the class. Did the secret agent successfully infiltrate the This message will self-destruct in five seconds. factory? d = 18.6 m y = 27.3 m Good luck. Factory Figure 1
