4) (4 points) The figure below shows the components of a simple bicycle's drivetrain: the larger front sprocket (chainring), the smaller back sprocket, and a chain that wraps around both. As the user pedals, the front sprocket rotates which causes the chain to move; the moving chain rotates the back sprocket. For this situation, assume that the chain moves over both sprockets without slipping. weas U I' rear front Rear sprocket Wfront Front sprocket Which one of more of the following quantities MUST have the same value for both the front and back sprockets? A) moment of inertia B) tangential velocity on the outside edge of the sprocket ") centripetal acceleration on the outside edge of the sprocket D) angular displacement E) angular velocity
