Hi, I have begun physics and we are seeing systems of reference as an introduction.Now I have a small exercise which I'm not sure of, I would need you to check if it's correct or not. There are two cyclists A and B. Suppose that you take place on a sidewalk and look at them pass. They move to the right and to a constant speed. What trajectory do you associate to the cyclists ? Rectilinear (so, one "x" axis.) What answer would the cyclist A give if we asked her to determine the trajectory of cyclist B ? Rectilinear also. Represent the trajectory of the reflector placed in the front wheel of cyclist B, such that you would see her from the sidewalk. The curves are halfs of a circle and I considered that the reflector began at half the height of the wheel.( so there's the highest point, middle point and the case where the reflector "touches" the ground.) THank you !
