The driver of a train travelling at 80.0 mph applies the brakes when he passes an amber signal. The next signal is 1.0 mile down the track and the train reaches it 72.0 seconds later. Assuming a constant deceleration, find the speed of the train at the second signal.

In World War II, there were several reported cases of airmen who jumped from their flaming airplanes with no parachute to escape certain death. Some fell about 20,000 feet (6000 m), and some of them survived, with few life-threatening injuries. For these lucky pilots, the tree branches and snow drifts on the ground allowed their deceleration to be relatively small. If we assume that a pilot's speed upon impact was 123 mph (54 m/s), then what was his deceleration? Assume that the trees and snow stopped him over a distance of 3.0 m.
Is it possible for velocity to be constant while acceleration is not zero? Explain.
