SUMMARY
The discussion centers on deriving the equation for time (t) in projectile motion, specifically for a football kicked at an angle of 46.0° with an initial speed of 23.0 m/s from a distance of 36.0 m. The equation t = Δx / (vi * cos(θ)) is established from the basic principle of uniform motion, where Δx represents horizontal displacement and vi is the initial velocity. The horizontal component of the initial velocity is calculated using vi * cos(θ), which is essential for determining the time of flight in this context.
