Concept explainers

Special Relativity

The theory of special relativity discusses how space and time are related to objects traveling along a straight line at a constant speed. Simply stated, as an object reaches the speed of light, its mass becomes infinite and it is unable to move faster than light. This interstellar speed limit has been the topic of much debate in astronomy, and also in science fiction when people consider how to fly over large distances.

Question

(II) A car drives straight down toward the bottom of a valley
and the other side on a road whose bottom has a radius of
up
curvature of 115 m. At the very bottom, the normal force on the
driver is twice his weight. At what speed was the car traveling?
