1. For this series of 4 questions, a rider rides in a car that is connected to a 4-m rod, and rotates about the z axis. The rod of negligible mass is subjected to a constant couple moment of M, and the engine of the car supplies a traction force of F. Neglect the size of the car. You will be asked to solve for different things. Please pay attention: the numbers may change from problem to problem since they are randomized. 1) If the total mass of the car and the rider is 145 kg, and the car moves at a velocity of 6.1 m/s, what is the magnitude of the linear momentum of the car-rider system in kg•m/s? Your answer must include 1 place after the decimal point. Your Answer: Answer Z M 4 m F

Report 2. The second activity basically involves the torque due to the weight of the ruler versus the torque due to the weight of the coins. You observe that the more coins there are, the closer the coins need to be to the pivot point (i.e. the edge of the table) for the ruler to be on the verge of falling over. Why? a. The lever arm of the weight of the ruler needs to increase while the lever arm of the weight of the coins needs to decrease for the two torques to balance out. b. The bigger the weight of the coins, the bigger the weight needed to balance it out; hence, more of the ruler needs to over the edge of the table. c. The more coins there are, the bigger the normal force magnitude that needs to considered in determining the total torque of the system. d. None of the choices

1. Perform analysis steps B.1. Derive an algebraic equation for the moment of inertia of the disk/plate by using the conservation of energy method. The variables in your equations should be the values you can measure (e.g., mass of hanger, angular velocities, angular acceleration, positions and/or velocities of the falling mass, etc.) and physical constants (i.e., the acceleration due to gravity). You should do this on a separate sheet and keep a copy as you will need it during the lab.

Looking for guidance to question based on characteristics/assumptions of experiment: Experiment background: For our dynamic measurement of the moment of inertia, we will use a vertically-mounted turntable that has a hub attached at its center, which has three grooves of different radius, around which one can wind a string. A mass hanging from the free end of the string provides tension, which exerts a torque on the turntable, thus causing it to rotate. By measuring the time it takes the mass to fall from its initial height to the table top (or some reference line just above it), we can find aa, its (linear) acceleration. From this we can calculate αα, the angular acceleration of the turntable. From the weight of the mass, and its linear acceleration, we can find T, the tension in the string. Once we know all these things, we can calculate the torque, ττ, and from τ=Iατ=Iα find I, the moment of inertia of our turntable platter. Assumptions made in this experiment:  - Turntable disk…
