The 1992 world speed record for a bicycle (human-powered vehicle) was set by Chris Huber. His time through the measured $200 \mathrm{~m}$ stretch was a sizzling $6.509 \mathrm{~s}$, at which he commented, "Cogito ergo zoom!" (I think, therefore I go fast!). In 2001, Sam Whittingham beat Huber's record by $19.0 \mathrm{~km} / \mathrm{h}$. What was Whittingham's time through the $200 \mathrm{~m}$ ?

Key Concepts

Unit Conversion

Correct unit conversion is crucial when solving physics problems, especially when different units are provided. Converting speeds from kilometers per hour to meters per second, or vice versa, ensures that calculations are consistent and accurate across the equations used.

Comparative Speed Analysis

This involves comparing the performance of two different scenarios by analyzing how an increase or decrease in speed affects time or distance. It requires adjusting the original speed by an incremental change and then recalculating the resulting time or distance using the kinematics equation.

Kinematics of Uniform Motion

This concept involves understanding the fundamental relationship between distance, speed, and time, expressed by the equation distance = speed × time. It is essential for determining any one of these variables when the other two are known, and it forms the basis for solving problems involving constant motion.
