SUMMARY
The discussion focuses on calculating the time of free fall and the angle of impact for an object dropped from a height of 100 meters under the influence of gravity. The relevant equation used is Δy = Voy * t + (1/2)ay * t², where Voy is the initial velocity (5 m/s downward), ay is the acceleration due to gravity (-9.81 m/s²), and Δy is the change in height (-100 m). The correct calculation yields a time of approximately 4.54 seconds for the object to reach the ground, confirming that the negative root is not applicable in this context.
