The skid marks made by an automobile indicated that its brakes were fully applied for a distance of 50 meters before it came to a stop. The car in question is known to have a constant deceleration of 20 meters per second squared under these conditions. How fast, in km/h, was the car traveling when the brakes were first applied?

Distance and Speed

The speed, distance and time relation forms the basis of study of motion. You will need these concepts in the study of Mechanics. This concept is applicable for students who are studying the following courses –

Question

1. The skid marks made by an automobile indicated that its brakes were fully applied for a distance of 50 meters before it came to a stop. The car in question is known to have a constant deceleration of 20 meters per second squared under these conditions. How fast, in km/h, was the car traveling when the brakes were first applied?

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.
