A car moving at 40.0 km/h strikes a pedestrian a glancing blow, breaking both the car's front signal light lens, and the pedestrian's hip. Pieces of the lens are found 4.0 m down the road from the center of a 1.2 m wide crosswalk, and a lawsuit hinges on whether or not the pedestrian was in the crosswalk at the time of the accident. Assuming that the lens was initially 63 cm off the ground, and that the lens pieces continued moving horizontally with the cars speed at the time of the impact, was the pedestrian in the crosswalk?
