SUMMARY
The discussion focuses on calculating the time required for a missile to reach its maximum altitude of 21 km, specifically in the context of the U-2 spy plane's capabilities. The relevant equation used is d = v_i t + 1/2 at^2, where d is the distance (21,000 m), a is the acceleration (-9.81 m/s²), and v_i is the initial velocity (0 m/s). The participants highlight the lack of specific information regarding the missile's speed and acceleration, leading to confusion in determining time. Ultimately, they suggest using the quadratic formula to solve for time, acknowledging the limitations due to missing variables.
