1. In the right figure, all points on the chain have the same linear speed. (i) Is the magnitude of the linear acceleration also the same for all points on the chain? (ii) How are the angular accelerations of the Rear two sprockets related? (that is, what's their sprocket ratio?) (iii) how are the radial accelerations of points From sprocket at the teeth of the two sprockets related? 2. A ball is dropped from rest and feels air resistance as it falls. Please sketch graphs about (i) its acceleration versus time; (ii) its velocity versus time; (iii) its displacement versus time
