Consider a railroad bridge over a highway. a train passing over the bridge dislodges a loose bolt from the bridge, which proceeds to fall straight down and ends up breaking the windshield of a car passing under the bridge. the car was 39 m away from the point of impact when the bolt began to fall down; unfortunately, the driver did not notice it and proceeded at constant speed of 19 m/s. how high is the bridge? or more precisely, how high are the railroad tracks above the windshield height? the acceleration due to gravity is 9.8 m/s 2 .
