SUMMARY
The discussion focuses on calculating the distance traveled by a cyclist accelerating at 1.1 m/s² from an initial speed of 4.2 m/s over a duration of 7.4 seconds. The correct formula to use is s(t) = (1/2)at² + v₀t + s₀, where 's' represents distance, 'a' is acceleration, 'v₀' is the initial velocity, and 't' is time. The final calculated distance is confirmed to be 61 meters, highlighting a common mistake of misapplying the formula by incorrectly squaring the entire acceleration term.
