A pulley is accelerated uniformly from rest at a rate of 8 rad. After 20 (s) the acceleration stops and the pulley runs at constant speed for 2 minutes, and then the pulley comes uniformly to rest after a further 40 (s). What is the total angular displacement made by the pulley in radians?

Q1. The image below shows an example of "absolute dependent motion analysis", where the motions of two objects depend on each other, and the goal is to find the relations in their motions (i.e., in their positions, velocities, and accelerations). Please put the suggested steps of analysis in the correct order. VA A B VB Differentiate the entire equation with respect to time, and extract the relation in velocities. Repeat for acceleration if needed. Set up a coordinate (s) along the direction of motion from a fixed point (O) or a fixed datum line. Represent the positions of the objects respectively. In some cases intermediate objects need to be considered too and their positions need to be represented as well. Recognize the constant length(s) and find the depending geometric relations between the position variables.

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. 3) If the rod is subjected to a constant couple moment of M = 840 N•m, and the engine of the car supplies a traction force of F=11•TN to the wheels, where t is in seconds, what is the magnitude of the angular impulse from the moment and the force to the car-rider system in kg•m2/s from t = 0 to t= 4.9 s?
