4. The figure below shows a bulldozer. Notice that the track on the bulldozer (the tread that wraps around the wheels) is kinematically similar to the conveyor belt in the previous problem. D E Suppose the person operating the bulldozer knows the distance between the two main wheels on the side of the vehicle. She looks out the window and, with the aid of a stopwatch, notices that the track is moving forward from her perspective at a constant speed v. Furthermore, as the bulldozer drives forward, the track does not slide or skid on the ground. In answering the sub-questions below, use the idea contained in Equation (2) and express answers in terms of basis (ê1, ê2). You may utilize results from Problem 3. (a) Using the terminology in (2), what does the quantity v directly represent? (b) Let C be a point on the track in contact with the ground. What is the velocity of point C as observed by a stationary person on the ground watching the bulldozer? Why? (c) Find the velocity of point E, at the center of the rear wheel as observed by a stationary person on the ground. What is the importance of this velocity to the person operating the bulldozer?

Learning Goal: In 1687, Isaac Newton presented three basic laws that describe the motion of a particle: • First law: A particle originally at rest, or moving in a straight line with a constant velocity, will remain in this state provided that the particle is not subjected to an unbalanced force. Second law: A particle acted upon by an unbalanced force, F experiences an acceleration, a, that has the same direction as the force and a magnitude that is directly proportional to the force.
