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 32 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 28 m/s.

How high is the bridge?
